If you log in or TP with the collar locked, you might trigger a security check failure.
Unfortunately I am away right now (yes, that pesky First Life thing, and yes, I’m sorry!), but will try to investigate and have a fix by this weekend.
Meanwhile, the only workarounds seem to be:
- wear the collar unlocked, for now.
- if you have HUD v6.2.x wear that (doesn’t matter if it says *OLD*) and wear the v1.0 collar, for now.
