Idea № 1
Need to limit count of resources that can be put in tar kiln, draw craft menu for tar kiln, ex: common liquid bar like for tanning tubes or cauldrons.
main issue in current solution is, we can (or not? honestly, i did'nt try) put to tar kiln infinite amount of fuel... and wait for charcoal, and wait for charcoal again, and wait again... i have waiting already 2 real time days...
Idea № 2
Just implement possibility to break production of coal and tar, i dunno how...
Thanks you!
