hi
i have a level with some 1000 blocks. now everything was fine till today. i wanted to add these tow blocks:

but they don't show up in the game.

i set no flags at invisible or else. an there are no error when compiling (just "plane too narrow" but nothing like "block deleted")
i tried to delet all errors but i don't think that my two blocks don't show up cuz of these errors.
now can anybody help me???
please
sam
