[0.9.13i] Disconnect and rollback on weapon swap bug in old fields cave

I encountered this bug in the Old Field Cave (The Great White Beast) in Cruel difficulty and was able to reproduce it 4-5 times before capturing it with Fraps.

Details are as follows

-Decoy totem gem is socketed into 1h mace
-If decoy totem is used and you then switch to bow, the decoy gem will simply vanish (as it is no longer equipped)
-If, however, the decoy totem is used and you switch to the bow while an enemy is taunted, your client will be disconnected.
-Only occurs in this cave

In my case, each time I was returned to the forest camp and had my accumulated XP in that dungeon reset.

It seems to be with any totem anywhere if it is equipped in the weapon.

I have a staff with spark/totem that I use for killing some mobs and if I switch to my Bow while creeps have aggro on the totem I get DCd and cant get back to that instance.

This is very annoying when doing maps.
