I posted this in the wrong thread before, sorry. The Blacksmithing wait time after making an item needs to be set in line with Tinkering and Tailoring. It pops the gump back up too quickly.
Supposedly it's based on a combination of the time of the sound effect, and the amount of server stress it causes.
Don't get me wrong...I hate the new wait times on Tinkering....but if I have to SUFFER making shovels....you have to SUFFER making Heater Shields. (oh wait...i fill BODs too )
I don't think it is confirmed as a bug. The BS gump pops right in time with sound effect for me. Use tool, select item, hammer on anvil sound, success/fail/gump all at once.
