8 Mix Strain will create random strain during process

[BigBintheAV]

I created a strain that is uses 8 mixers. I have the chemist mixing and moving them to the next mixer. However a mixer will randomly want me to name a 'new strain'. But its nearly identical to the one that was already created, sometimes the exact same. It acts like a new strain however when I look at the ingredients after I name the 'new strain' the output is the original strain. I want to be able to set it and forget it while doing other things, then come back to a shelf full of product. Only I come back and it stuck wanting me to name a strain. Anyone else have this issue? OR is this part of the game where it just throws in a random mutation??

Played 5 savegames (to mid/endgame 3 in soloplay and 2 in multiplayer +2 in demo) and i never had this issue. It could happen if u fill up the wrong mixing ingridiens in the wrong shelf.
