This is not World Editor crash when save but It is Saving the game in the real gameplay and it crash.
I tried to save it after the map start and It works fine then I wait for about 15-20 minutes and try to save it again. This time it crashed.
at first I think it crash because I added 3 Jass code to the map. you can see it from this link:
[JASS] - I can't save my game and I think it's because of These Codes memory leak but I don't know how to fix it.
Edited1: I tried disable all 3 code listed below but the crash when save the game (not the map) still occur. I just learnd Jass for about a week. I have edited other's code to my liking for my custom map. this map game saving was fine before. but after I added and edited 3 of these code in...

but after I tried disable all the codes above. The crash still occur.
so I tried play different custom map and wait for about 15 - 20 minutes. No crash occurs.
I will attach the map file below. This is not my map the credit goes to EotA: Exodus (v E1.5.19c)
The creator share the unprotected file. I like adding my own custom to the map.
