Was playing in ATM9 trying to pull off a lich bit, figured this potion was key... however, drinking the eight minute potion causes a crash to desktop, strangely, the splash potion does not cause this effect, may be related to another mod, however, worth reporting.

should be released now

i was going to say "try to update" but i havent't release the fix for it yet sadly. it's a confirmed bug and fixed indev already
