Miscellaneous: Tradeskill combines - Crashing

[Sylexis]

I seem to crash if I try and combine with something on my cursor, like I was sucessful on the last combine and didn't notice.

I did this once on a brewing barrel, and twice on an oven, both times in Rivervale, both times I got the same message that I couldn't combine with something on the cursor and then I was immediately booted to the login screen.

In theory I can repeat the bug every time.
