I have little modpack I've made myself that includes i. a. ComputerCraft & InfernalMobs. What the problem is, when turtle is focused on attack only (shortest infinite while loop that repeats attack()) and in front of him, from spawner, appears mob with upgrades, game crashes. Tested this on both SMP and SSP, updated mod today and tested again.
What it appears to be, infernal mob debuff, like wither, blindness or gravity, interfere with mod code and isn't working properly.
I can't do anything by myself, config can't help, but I'd like to be able to play with both theese mods without turning some entities enchants in IM config, like I did to be able to keep my mobfarmer running.

PPS. I can't do any other mobspawner grinder because SoulShards Reborn seems to stop the drops if spawneb mob isn't killed by human or turtle.
