Running multiple clients is not supported.

Running multiple clients is not supported.

When did that become an official stance of the devs?

[Granger]

No idea, but in case Loftar actually wanted to support it then he wouldn't have coded the file access as being exclusive, would he?

Or maybe he did not even realize that such a problem as this would even occur.

Could be an issue with Windows that he isn't aware of or a myriad of other things. When I asked about it he said he supposedly uses proper file locking to coordinate multiple access to the files.

May try to look at it. Any idea on how to reproduce it, beyond what is described in the OP?

2 Accounts -> down in the mine -> one stands there and the other one is mining. (They have to see each other).

Almost bet the map "changed" while both clients were trying to update it for the same thing--a tile was removed thus forcing a map update.

Running multiple clients is not supported.

As far as Granger's remarks... it's not a design feature, so no, not directly supported, but loftar does do what he can so people can if they want. It's not the first time multi-boxing has caused client crashes that have subsequently been fixed.
