[ADDONS] "Two of my subscribers said: Your map is crashing my game!"

as a title say I got two messages from my subscribers about crashing. I have just this information: Their game crash at downloading status. If they remove subsciption everything works fine. Other addons don´t do that. So, where is problem?
Any ideas what si wrong?

Off the bat, you mentioned it crashes their game when it downloads. Most player’s games have issues downloading larger addons while the game is in progress. Personally, I wouldn’t worry about it too much. I mean, the map is 141M(Fairly large for a Gmod addon)
I didn’t crash while downloading it. 3/4 of the Gmod community has a bad PC or internet, unfortunately.
Hope this helps.

It’s their fault for having too many addons/having a different addon that causes errors.
