Modding tools bug.

[Indar]

Hi, when I start to test my map, I see this trouble. I don't know what happened, I didn't add any big entity. What's problem and how can I solve it?

It's generally a better idea to test your maps in custom battle rather than in the editor test, I would assume that the missing terrain is one of many editor test bugs that happens.
