Issue with Minecraft Forge crashes.
I understand the issue with your Minecraft modpack. It seems the problem might be related to a specific version of TConstruct that doesn't support it. You mentioned that using TConstruct 1.7.10-1.8.7 works, but when you use only that version and then apply corrections, it functions properly. This suggests there could be a compatibility issue with a particular mod. Checking the official documentation or forums for the modpack might help identify the correct version or workaround. Thanks for sharing the link!
It appears to be a fluid problem with tc and necromancy. Both mods probably have a fluid with the same ID, or a material property is being modified that cannot be sustained by the original mod. Removing necromancy should fix it. If you don't want to do that, you would need to look further into what in necro is causing the problem with TC.
