[JASS] 'Double Free' group?

[Bubba Ex]

In NewGen editor I made some code and when I tested it it didn't work and cam eup with the debug message: "double free group: g" What does double free group mean?

It happens when u want to destroy a group which is already destroyed.
like this:

• Double free group
  • Events
    • Time - Every 2.00 seconds of game time
  • Conditions
  • Actions
    • Set TempGroup = (Units in (Playable map area))
    • Custom script: call DestroyGroup(udg_TempGroup)
    • Custom script: call DestroyGroup(udg_TempGroup)

It happens to me often too.

It can also occur when a null variable is set to null.

Does that slow your code??? I have heard it does, but I'm not sure

I think it crashes the thread and causes lag

Hmmm, o ok, so I should try to get all the double frees
