Excuse me if this has already been asked, I looked through the bug reports discussion with ctrl+f and didn't find anything. It's such a pain that there's no search bar in the steam workshop discussions...

Anyway, sometimes when I transfer items over to the tek refrigerator, it puts the spoil time at 50% instead of 100%. I have had this issue from time to time before, but right now every item that I test has this issue.

It happens when I transfer them one by one, in stacks of 5 and in full stacks. The issue persists when I move them back to my inventory and then back into the fridge. Even a 100% spoil time item gets cut to 50% when I transfer it to my inventory and then back.

A different issue is that sometimes the spoil timer just does not change at all from whatever % it is on, but I think that happens when I bulk-transfer only, using the arrows up top of my inventory. Normally, just clicking the item and hitting T to transfer the item or stack works to put it at 100%.
