Upon opening up my game a few hours ago I noticed that my sunset sarsaparilla star bottle caps were no longer in the misc section of my inventory, perplexed I was able to find a few more after looking around but as soon as I picked them up they were gone from my inventory again. Has anyone else had this issue?

I have a similar problem where my star caps are not being added when acquired from a Sarsaparilla bottle.

This happened to me but only after I'd finished the quest to turn them in.
