Hi I'm back again because I've experienced maybe 3 new bugs while I was playing with CofhCore 4.1.8.12, and MFR 2.9.0B1-233. In fact I'm still playing in a modpack with a bunh of other mods (tell me if you want a precise list), when I place a grinder or a slaughterhouse it just disconnect me from the map as if I'm playing on a server (so no crash) and I don't understand the issue seemed fixed but I'm experiencing it with the latest builds from curseforge. So here are the errors with both block :

GRINDER.txt
SLAUGHTERHOUSE.txt

And the second bug happens when I'm placing a smasher, my game just crash and I don't know why, so here is the smasher error with crashlogs
SMASHER.txt

yeah, so all of these are one thing - bad mapping to obfuscated name for rand field - my bad. I will get a fix done, but it will require another build of cofhcore so it may take a few days to release

Actually looks like skyboy has already fixed this in dev so once that change is released with next release of CoFHCore this issue will go away.

ok perfect :)
