In short: If you have a PSI CAD in your inventory the search bar in RFTools modular storages has weird behavior when updating. Nothing huge, but can be annoying.

Hmm, did you also report this with PSI? Could be some kind of interaction but would be nice to know what exactly is going on on the side of PSI

Sry, forgot to post it on the PSI side ^^

Thank you for taking the time to create this issue, as we're no longer supporting versions below 1.12, I'm going to go ahead and close it but if this bug seems to continue over to newer versions, please do report it again so we can investigate the issue further.
