I'm having this exact issue. Was it never fixed or is this a load order issue?
Edit: Not a load order issue. Just disabled everything but Rimatomics to test it.

+1. I came across this thread before I tried to change the order of mods or disable something. But still:

Experimented a bit. The only way around is to disassemble the storage pool

+1. The bug doesn't seem to be tied to the storage pool for me but rather some other Rimatomics structure. Maybe it's outdated mods? Not sure.

Edit: Seems like there's no way around once it's set off. The cause is either a research reactor, having any completed Rimatomics project, or the reactor core. Not good.

Edit 2: The cause seems to be Style Change Anytime. ???
