Anyone had any luck with getting this achievement, Pillar of Community to unlock? Mine is stuck at 5/5, but isn't triggering as being completed like the others. I've tried resetting my progress, restarting the game, replaying already completed levels and saving created levels with different author names. But nothing has worked so far :'(

I'm playing version 1.0.3, through GOG Galaxy on Windows 7.

I've the exact same problem. There's a discussion on steam where an user mentioned a similar issue, but it seems to be solved on that platform.

v1.0.3 was uploaded on 2021-07-06, before the steam version updates, so I suppose we'll have to wait for a new build here on gog.

Thank you for this information.

Decided to post this on Steam, hopefully we'll get a response from the dev.

Same here :( I've completed 9 custom levels (info from stats screen), but it's still locked.

I even lost all achievements I had reached so far. The Linux build seems to forget earned achievements between game starts. This screams for a fix.
