I need some time off my own construction, I'll try it 
My opinion:
Ok, FIRST STAGE, I got stuck and no way out, could not change gamemode or break any blocks. Cannot use /kill = Stuck for eternity
Ended up leaving the map.
Where: There is half blocks under me, blocks with half blocks on and blocks too high up around me.
I assume the wood was meant to catch on fire?
