I didn´t played for a while and just updated the mod from 0.1.9 to 0.2.7 and it turns out to not be competibile
- Lost underground Mag eg. all Underground Belts got deleted
- Breking eristing underground Ports will casch the Game with the error:

beltlayer::on_player_mined_entity (ID 56)
beltlayer/Editor.lua:160:attempt to index
local'container' (a nil value)

I will try to update the mod version one by one and will update if i was sucksesfull or not.

Edit: Updating to 0.2.0 / 0.2.1 / 0.2.2 / 0.2.3 and loding a map will resut in a crash
but 0.2.4 works fine and from theare I was able to jump strait to 0.2.9
