I tried to convert a trade to a sink trade just now, and it gave me this error and kicked me out of my save. It seems specific to the one core that I was trying to convert for whatever reason. All the other hexes I've tried so far convert just fine.
The trades it was trying to convert were 6 petroleum gas barrels, 8 lubricant barrels and 1 coin for walls, boilers and wood, as well as 3 light armors, 3 firearm magazines and 4 iron chests for 3 low density structures, and finally 62 copper plates for landmines, concrete and iron ore.
The mod Hextorio - Build in hexagons (1.5.8) caused a non-recoverable error.
Please report this error to the mod author.
