I have posted updates to Aesthetics and Fusion that improve mod compatibility with other mods that provide copper, tin, bronze and steel ingots, namely "Thermal Foundation" and "Immersive Engineering". Basically, if you have either of those two mods installed, and don't care about mythril, adamantium, onyx, or fusion alloys thereof, you don't need Simple Ores installed, and/or can use the other mod's ingots to make stuff in Aesthetics and Fusion. This has not been extensively tested (hence beta), but I have successfully tested making Fusion bronze ingots in the Fusion Furnace using Thermal copper and tin ingots. You will probably have to manually enable the items and blocks you want in the config file, because the default config setups for Fusion and Aesthetics disable copper and tin stuff if SimpleOres is not loaded, and disable bronze and steel things if Fusion is not loaded.
For other mods not named above, you'll have to make sure the other mod loads before Fusion and/or Aesthetics, or the "foreign" ingots will not be detected. Obviously, this only works with mods that bother to use the ore dictionary for their common metals, but as far as I know, most 1.12.2 mods do so.
There was also a fix to doors in Aesthetics--I fixed a bug that prevented copper and tin doors from having configurations, and thus, prevented them from existing.
SimpleOres and Netherrocks have been updated to 1.15.2 and back-ported to 1.14.4. Copper buckets are still a bit wonky, but they'll carry water. Modded shears work. The Nether Furnace works.
I am NO LONGER MAINTAINING ANY 1.12 mods or older. The mindset & style is just too different from 1.14+ coding; I can't juggle two different coding methodologies on top of my paying job's demands, so if you want upgrades to 1.12 stuff, you can pull the source code from the 1.12 branches on my GitHub.
I am working on Fusion and the other mods will be coming along as time allows; the current "situation" gives me a bit more time than usual.
I have pushed out an update to SimpleOres, both 1.14.4 & 1.15.2 versions, that does a couple of things:
makes copper and tin ore a bit more common, more in line with the original design. As this is controlled by config file settings, you'll need to either delete and regenerate any existing config files, or change the settings yourself. The default settings are shown in the new Wiki.
rolled parts of akkamaddi's Addenda into Simple Ores; specifically, it is now possible to find Simple Ores items in some chest loot. This option is configurable (i.e, you can turn it off if you don't want it). As I also maintain akkamaddi's old mods, and everything is GPL-licensed, I gave myself permission to do so.
I plan to add the same feature to Netherrocks and Fusion.
I plan to add akkamaddi's fusion recycling recipes to Fusion. (I have, in fact, already written them, but needed to implement the loot injection feature in Simple Ores).
