Mining Limestone issues with Excavator detecting terrain.

Issue description

Issues Mining Limestone. Basically the small Excavator gets lost and starts mining in one place and then cant detect anything then stops and tries in another location in a giant circle.

Reproduction steps

Really not sure.. I sent a saved file to hopefully assist with this issue along with a video.

I discussed this with them on discord and resolved it (https://discord.com/channels/803508556325584926/883590993063051275/1148232543670378558), but it might be good to give a notification to the player that the excavators can't reach the terrain, put in a red outline for places that can't be reached like dumping (maybe, most of the time it would likely just be annoying, so maybe a toggle?), or something else. Also, it's a giant pain to get the mining designations started on diagonal slightly sloped terrain, but I don't know if there's any way to fix that.
