I see your still on MC 1.8, there might be some improvements already that you can't take advantage of since I've moved to 1.8.8/1.8.9.
I guess you are waiting on some other mods that have not made the move yet? Hmm.. If you were still having the issue on the latest builds ( on 1.8.8/9 ) I would really like to get a hold of the world for testing, but with you being on the older version its hard to say if the issue still exists.
I can certainly look at the world, you have a lot of really complex blocks, so it would probably be helpful to analyze either way, having more data can only be helpful. So feel free to send it my way, It might provide some clues for improvement even if some of the issues were already alleviated.
Hold Shift to See Bit in block form.
Show Textures for the faces of the block on the bit model.
Re-wrote Collision Code for chiseled Blocks to be more specific.
Tweak Bounding Box Displays, display flat box when using a bit on a surface that cannot be chiseled.
LMENU/RMENU are now Localized.
Add Creative Tab Search to C&B Tab.
Fixed performance issues with Bit Bag Gui.
Pressing Q on a bit bag slot no longer drops items from the players inventory.
Patterns now work on multi-part blocks.
Fix Bit Item Names for logs.
Edit: I ended up having to pull the build because of some super broken ray-tracing issues.. I've fixed it and will be re-releasing after some testing.
Here's an idea: the Pattern Punch. When you put a pattern in, it converts it to some discrete string that represents the positioning of bits and whatnot, then saves that pattern to the player's personal library. Each entry in the list has a little icon rendering what the pattern creates, and with the touch of a button, it can be translated onto a blank pattern card (blue or red tinted for respective types). That way, you can transfer it from world-to-world as long as you have a Punch, and others can save to their libraries if you pass the pattern to them. Possibly a renaming system, as well.
EDIT: Unlabelled patterns would go 'pattern 1', 'pattern 2', otherwise it'd be sorted alphabetically.
EDIT2: For 'superusers', ideally there would be a way to access + copy the 'string' and then paste it to be interpreted, so people could share their designs in spoiler tags.
I've still not ironed out the details, but the current idea is some kind of block/gui where you can put patterns in, and get patterns out, basically a means to import/export into the chisel design pattern items, with the outside world, possibly even storing multiple patterns per "string" and potentially having support for things like "paste-bin" where a user can post all their fancy creations to one "library" and people can tap into it to reproduce their designs onto patterns in game, with the potential to write to negative, or positive items.
Its probably one of the next things I'll be working on but i've been a bit swamped time wise so it might take some doing before its ready.
I have a lot of trouble placing chiselled blocks. For some reason they want to be placed inside a block below it, not on top of the block. I used the chisel to make a simple vertical slab (8x16x16 bits) and I created a positive chisel design. That was all very intuitive and easy to do, but for the life of me, I can't place the slab where I want it - I always unintentionally place it inside other blocks (either below the desired spot or behind it), partially destroying these blocks and making a mess...
And please don't perceive my whining the wrong way - I really think this is one of the greatest mods ever created! It could very well be that I'm an idiot, but I really can't figure it out.
Edit: here are screenshots illustrating my struggle.
At the moment positive chisel designs are only used to chisel existing blocks, ( you can't place new blocks with them )
I have plans to add that as a another option however, in the mean time what you probably want to do use use the positive design with a big bag( with the right bits) in a crafting table and pull out chiseled blocks that you can place in world.
Is there anyway to enable debugging or to get more information into the console? I have something conflicting but only on SMP, right now, nothing shows up in the server console any different than it would otherwise, but nothings crashing so I'm not getting any logs.
Basically I take a valid block, chisel a piece out of it, sometimes it doesn't appear to do anything, othertimes the block turns invisible yet is physically there, kind of like 1.7 world holes used to make you bounce when nothing was underneath you. I'm not quite sure how to diagnose this with no console feedback and the same sets of mods working in singleplayer.
Either way I don't get the bit,
I have also at this point sync'd all the mods on the server and the client, as well as the configs.
I'm running forge 1710, with chisels and bits 1.8.4, however I have duplicated the behavior in 1.8.3
