Dear reader, I hope you can help me with this frustrating problem.
I host a (Forge) modded Minecraft server and had to remove a mod that put too much modded blocks in the ground.
Since that would leave a lot of ghost blocks in the files and holes in the world, I decided to replace all ghost blocks with regular stone in MCEdit2.
This worked great, but for one detail...
All existing modded blocks in the world are calculated as opaque for the lighting calculations. Leading to mobs spawning in broad daylight.
When I check the light levels you can clearly see even obviously transparent blocks are blocking light.
When updating the light level with a torch, or waiting some time besides the block, the problem seems to go away for the block. But when I relog, the same block exhibits the problem again.
Restarting the server also does not help.
Does someone know how to fix this? Or maybe give me a few pointers where to look if I need to write a mod to do this?
I would be most grateful for any help I can get.
With kind regards,
