Fixed issue with SE_StackingCommand_Overwrite

Browse Source 
SE_StackingCommand_Overwite uses the calc to figure out the slot to check.
Seems that calc 202 is slot 1 and 201 is actually something special. It
could be any slot, but need further investigation, for now, just ignore it.

Secrets: Fixed an issue related to a zone crash where the count of the abilities in an AA was 0, leading to a size 0 buffer issue.
