I had/have issues with heap corruptions and I got some error from your mod but its maybe not your mods fault

Disable the mod if you think its causing you issues. Its pretty old now and I'm no coder so I cant update it. Just keep in mind if you disable it you may see placeholder cubes around the map.
As for the "Heap corruption" this is due to more than one error at once so probably something else.

Is it you that is causing my heap corruptions?

sorry dude but your mod script is broken. i don't recomment this mod. the idea is good but without update is just more forgotten mod sitting on the workshop

Also having the same issue with both mods enabled

I'm having the same problem I have both mods installed

Yes, sorry. I have the other mod activated. It happens randomly after playing a few minutes.

@finnr - just out of interest - you did enable the other mod as well - the uk style house assets - it is clearly marked as a required item. I appreciate it doesn't clearly say that you need to enable it as well in the description.
