Tick ​​crash

[Samlegamer]

Hello I have been using food funk for some time and have noticed a crash that occurs randomly when I move away from my base which obviously contains a freezer.
Sometimes my backup crashes but I manage to reopen it easily (that's when the crash involves HashMap) but otherwise I have a second crash that occurs and which is almost never removed (HashMap $ HashIterator) and I can no longer reopen my backup.
I tried alternatives like debug mode or even daring debug but I have the impression that nothing prevents this bug: /

For info here is the version of the Mods:

• Forge 1.12.2-14.23.5.2854
• Food Funk - 1.12.2 - 4.9.6
• Wumple Utils - 1.12.2 - 2.12.9

I wonder if an earlier forge version would fix this bug 🤔

I managed to counteract the final crashes of the game with these mods:

Chunk-Pregenerator : https://www.curseforge.com/minecraft/mc-mods/chunkpregenerator
VanillaFix : https://www.curseforge.com/minecraft/mc-mods/vanillafix

Daring Debug can be a solution for the most desperate people.

When I say crashes, I mean only the definitive ones, you will crash sometimes at random.
Maybe also a mod that checks that the number of ticks is always stable at 3 by default could fix most crashes.
