Oh yes, everything did work fine after last problem, I did made few clicks and bushes were appearing, saved level, closed game, did other things and now started the game again, but I found out there was no editor starting. In console there is error about forest editor starting and about forest brushes, main problem being fbe = nil I guess. I did check and all the files and data in files related to forest brush I created earlier do appear to be fine. Although I did notice a new file in forest folder, apparently editor had converted my Blender exported forest items to new format, old file had extension .for_bak My looking for things being off did not produce much of result, in fact I found to be quite stumbled by this error as I have no idea what data this fbe should have, so I thought I post here and perhaps there is some findings from all this. It can be some mistake I have made regarding editing of map or files, so I attached whole map there if it needs to be examined, but probably figuring out what this fbe is or should be can lead to tracks of how to fix the issue. fbe, Forest Brush Editor? Maybe I need to remove all forest brush files and just create new ones, but should editor fail to start because of whatever is causing this?
