It sort of comes and goes, no other loot-specific add-ons or weak auras running.

Elv conflict? Check out the code from GogoLoot on this? We didn't have an issue here.

Probably ElvUI related. I don't test ElvUI on everything I make, I usually wait for the user reports. Also: I will always write code myself unless there's a library available :) Not to reinvent the wheel, but mostly to avoid fuss and to make sure I can always stand behind what I made

@Gogo1951 can't reproduce this even after 50+ trades using ElvUI, so if you find a way to reproduce this please let me know.

Try trading in combat. Still happens. Running and opening a trade on the fly, while in combat, and you lose the Announce options. It still announces but you can't see the interface.

Should be fixed, reopen if it still occurs!
