What is the correct way to remove concrete from a given position?

The surface object has methods like set_tile, I can't figure out how to "unset" a tile back to what it was before the concrete was there.

I can confirm the desync issue, but have no idea why it's happening. Is there a guide somewhere that explains how to diagnose desync issues?

I don't have a link, but gold at least is intended to be hard to find. I've been playing with RSO on as well and sometimes the nearest gold patch to the base is several minutes drive by car. Load up!

I'd love a pull request implementing non-built-in cargo wagons! I had a hard time figuring out how to determine the capacity of a container, but I'm sure it's possible.

When a mod calls set_request_slot on an opened requester chest, the UI for the request slots does not reflect the changed value until the chest is closed and re-opened (or other user action on those slots).

/c game.player.opened.set_request ...

Opening a tank or car and invoking

This restriction seems arbitrary since tank and car inventories do support filtering.

Didn't think to try getting in the car in my isolated repro. Now I know the workaround! Thanks

Steps to reproduce:
* Load save game
* Open car inventory
* Middle-click any car inventory slot

I cannot reproduce this in a fresh map, but my friend also experienced this with a tank in a different ...

I've found the tank to be great, though maybe not in the way it was intended.

If you have a personal roboport (which you're going to have anyway) and poison capsules (good use of coal), the tank is great even up through Big biters, worms, and spitters. You're immune to poison damage while inside ...
