Hello! Created a sequel to the legendary map The_Descent 3, threw a friend to test it (He is on version 0.19.4.0), and everything is still unchanged for him, as on The_Descent 2 (She was taken to continue the creation of The_descent 3) I did it on 0.15.0.2, because the PC does not export new versions. (Through the F11 editor) Tell me - what is the problem and how to fix it?
