not sure if its related with Advance Machines or the mod in question
if u macerate Monazite from MFFS in a rotary macerator
u get extra forcicium from it if one output slot is occupied with 55+
forcicium, u get to complete that stack and the 10 forcicium - that u
normaly get by macerating - on the 2nd output slot.
Explanation
if the 1st output slot has X space while X<10 then the final output of macerating
mozanite = 10 forcicium (normal) on the 2nd slot + X forcicium on the first slot (completing the 1st stack - bug)
example:
1st output slot as 60 forcicium, after macerating 1 more mozanite u get 10 forcicium on
the 2nd slot + 4 forcicium on the first slot
1st output slot as 56 forcicium, after macerating 1 more mozanite u get 10 forcicium on
the 2nd slot + 8 forcicium on the first slot
this has been reported on MFFS as well due to the fact i dont know which mod is causing it
