As you can see, there is another strange bug here. It seems I can't craft anything. Because when I exit the Arcane Worktable GUI, the wand will always disappear.
This is using thaumicwands-1.2.2, and forge 14.23.5.2854.

could you also provide your log file when doing this ?

Another picture with version information, although it's in Chinese.

When I try to take the wand on the arcane worktable before exiting the GUI, the staff will still disappear.

This should be fixed in v1.2.3 looks like something went wrong when adding the additional slot to the worktable.

Still an issue in 1.2.5
