It is good, that you guys want to report some bugs, but don't report this bugs in a topic about Walls Ground.
If you want to report a bug you have 2 possibilities:
Make a topic about this map (There is already one for Gobi)
Wirte the developer a personal message (for Gobi it is @Ruud033 , for Tomb it is @TK0104)
If you don't do this, the developer maybe don't see it and the bug wont be fixed.
