MOD version UPDATE - CSH_v21.2.11
- still for A21.2 (b30) !!!
- fixes, improvements - as usual
- thanks to tips from ちびにゃ, i managed to make a normal installation of the doors 
- dms is disabled
(this version is not compatible with worlds and saves from the previous one)
Pay attention: if you install a new version on top of the previous one, then first erase the "Prefabs_CSH" folder, so that files from the previous version do not connect!
Note: due to the difficulties in using github and gitLab, i am switching back to Yandex-disk. Therefore, in the modLauncher remain old version.
Links to the new version are available on the OP.
