I've made a simple Hero Save Code for Multiplayer Maps.
You will now know whats special about it.
Well it isnt much different from other SaveCodes but one thing is Special:
All you need to do is copy the trigger to your map and it instantly works with custom heros, custom abilities e.t.c.
So in 2 seconds you have a fully working savecode in your map

Get the Trigger here:

I havent extensivly tested this trigger, if you see any problems you can either PM me or write it in the comment section of the Trigger
