i just recently was running out of dirt in my base, so i decided to start cooking dirt using the material transport.
however, after reaching 1840kg of dirt in 1 tile, it started to build upwards with 20 dirt in each new tile above.
Steps to Reproduce
cook slime using conveyor rails, once at 1840 kg you have a growing tower. see save file.
