Hi I keep getting this error

The mod RP Steam Roboports (0.0.7) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event rp_steam_roboports::on_nth_tick(1)
LuaRenderObject API call when LuaRenderObject was invalid.
stack traceback:

Oh no. That really stinks. I bet it's blocking you from playing that save. Did you start this base before space age came out or after? Can you upload the save file so I can reproduce the error?

I'll look into it in the next day or so. Today is a holiday so it probably won't be fixed today.

Its is a new save with space age
It happens when I toggle Gridlines Mod or Construction Planner Mod in the shortcuts after I have placed a Steam chest if I remove the chest it no longer crashers.

That looks like a map seed string, not a save file. I can't debug it with that. I'll try adding some null checks anyway and see if that helps.

The Construction Planner Mod does a lot of weird stuff with ghost entities so it probably breaks some basic assumptions with my code.

I added some more null-checks. I hope that fixes it

Ok thanks
