A member commented on my Ancient Hero Arena map that siphon mana crashes the map so I went there to check it, and I still couldn't fidnthe problem. I isolated the spell to maek sure it's the one that crashes the map, an it is. I checkked all fields, found some msitakes, but still can't find the reso for the crash. Can you help here?

EDIT: Why am I thinking that the neutrl hostile siphon mana crashes the map, but the hero one won't?

Could you post the triggers please? Are you siphoning from/to a unit that doesn't have mana? That is my first guess if it's not simply the choice of base ability.

There are no trigger, as you can see, if you opened the map.

Well I tried the map and it crashed once it finished loading yet when I removed the ability from the knight, the map loaded without any issues. I replicated your scenario in one my messy test maps but I didn't encounter the same problem. So I decided to copy the ability from your test map into mine and lo and behold, my map crashed. Didn't even load. :/

It's seems there is some sort of glitch with that specific copy of the ability you have there, so I'd recommend you make another copy like I did and base your spell on that. By the way, are there any more details that you could provide us on how the crash occurred in your Ancient Hero Arena map?

P.S.: In future, you might want to add some comments in your test maps to explain what exactly is going on.
