mhm, the only Array i use is to find pointer of free space inside vertex-buffer (to avoid rebuilding buffer if new tiles added/removed), thats here: https://github.com/maitag/peote-view/blob/master/Source/de/peote/tools/Holes.hx#L40
but i guess the problem is somewhere in Timer (frequency of spawning) or maybe i did mistake in text-output (that clears its buffer all the time), i wanna check this
