The /reset beta cheat command now resets talents properly, removing the need to reload the save
I think you mean /respec, and I think you introduced a rather nasty bug here.
I summoned Gold Charge Snowman and Cloud, then hit /respec. Cloud poofed, Snowman didn't.
I tried to desummon Snowman and couldn't. Save and quit, log back in, summon snowman. Can't desummon. Go to another save file, summon snowman, can desummon him. Close the game, reopen, go to the initial savefile. Summon snowman, can't desummon.
Something is perma-bugged on my test character for snowman desummoning.
On the plus side, I got to move like 15 bug reports into the solved forum!
