startup crashes both on version 1.15.2-0.1.14 and 0.1.13. I looked through the log and crash report and neither seemed to lead directly to this mod but when I revert to a previous version everything loads fine. I do have many other mods installed but productive-bees seems to be the problem

I need the latest.log to find out what's causing the crash

latest.log

I know it looks like an issue with cooking for blockheads but I uninstalled it and still got a similar error

Try updating forge to the latest 31.2.31

I'm gonna rollback some code changes that only work on later versions of forge so it can run on the recommended version again, but for now, updating will fix it.

Yeah updating forge worked. I should have thought of that, thanks!
