List any other mods required to reproduce this issue. Test by running the game with minimal mods.
I have done meticulous testing of my modpack with almost 500 mods, and have done confirmatory testing to narrow it down to just all these mods installed.

Telling me something crashes without providing a crash report is useless. Give me a crash report or I cannot help you.

oh right I forgot, i thought I pasted the pastebin link so here it is:

Looks like someone is returning a null itemstack as a result from the brewing itemstack getter. Null itemstacks have been illegal since 1.11, so someone is doing something dumb. Not certain who as the stacktrace does not tell me which recipe is to blame

Edit: looked in their source code for about 5 seconds, its mc survival essentials

Closing as fixed in the other mod.
