Chemicals mix

[Jemand]

Hi

I have a problem, maybe a bug:

I found all chemicas and mixed them in the pot... then i went to organic tissue wich blocked my way... so i use the chemicas... after the tissue disappered i thought: "hm... maybe ill need this mix again soo, so lets make some new"

and so i went back to the lab and tried to make some new... but i couldnt. So i went back to the (dissapered) tissue, but it already regrowd...

So i cant make a new mix and the tissue blocks my way...

any ideas?

edit: and i cant load a save were i still have my mix, because it is already overwritten

(sry for my bad english)
