We're seeing a LOT of people complaining about getting a "can't create inventory item" error message in Firestorm support group, even with fully loaded inventory. I got that message myself repeatedly on various SIMs and it keeps going on.
There was an unscheduled server maintenanceearlier today and the issue is supposed to be resolved.Perhaps not the same issue, but there definitely is one going on.
File tickets folks, LL need to know about this issue.
