Shortly after deleting chunks Mining Drones causes a non-recoverable error, even after changing the raduis of detete chunks to 10 so none of the mining drones are in deleted chunks. Not sure if it is mining drones fault or if its just the first mod to cause a problem.

This bug doesnt happen if the radius is large enough to delete 0 chunks but as soon as one chunk is deleted it crashes:

Oh, Its deleting the chunk that has my 'proxy chests' in it, which is the chunk at position -1,000,000, -1,000,000

I see, I'll ask the mod author if theres a way to blacklist chunks, if that doesnt work I guess ill just go to -1000000 -1000000 and build something there. Thanks

Hey Klonan, If I may make a suggestion. You could move your proxy chests to another surface. That way there isn't a chance that the player may build in that area and any mod that manipulates the 'nauvis' surface will not interfere with your mod.

Having another surface exist adds a lot of overhead to every update, since it also spawns extra managers for updating things, like electric networks, pollution, fluids, transport belts, etc.

I will probably move the proxies somewhere in a future update

If the chunk where the proxies are was charted, they should be detected and not deleted. They would also need to be on a player's force.

The chunk isn't charted, also they are on neutral force at position 1,000,000, 1000,000 (Not -1,000,000 as I said earlier)

I'm adding detection of your mod and white-listing that chunk. If you do change how you're handling the inventory, please let me know.

I dont know if i have the same issue then you guys but this is what happen if im deleting one Special mining building while all other buildings are good with deleting and rebuilding.
Ive tried taking all drones and materials out before deleting it but same error happens.
Like i said its just this one building

Can you provide a save game?

I have removed the proxy inventory system, so deleting that chunk should be fine now
