Cargo Depot stays in Ship access is blocked after a ghost pump is removed

Issue description

The cargo depot (4 port at least) can get permanently stuck in a "Ship access is blocked" state if a seawater pump (tall) is placed within the vicinity, but not actually blocking the port's ghost tiles, and then removed before it is constructed.
The "Shovel ground..." button does nothing at all in this case, it simply does not function.

Expected behavior

Well of course this just should not happen, but more importantly, the cargo depot should be able to recover from a locked-up condition such as this.

Reproduction steps

I've attached the save file, you should be able to see the broken cargo depot and go from there.

Game version

v0.4.9c

Thanks for the report. By any chance do you remember any other operations around the broken cargo depot that were blocking it? Maybe some terrain dumping, or other buildings? Or you just constructed depot and then a pump, without any other ocean-reaching buildings or terrain operations?

This was fixed in v0.4.11. Thanks for your report!
