Claim depth randomly going above where the player has built

[MrShack]

What happened:

The player has built underground (Y5 to Y30) and the claim automatically expanded just like it's supposed to. The issue is that it randomly "resets" the claim to be ~Y15 and up while leaving anything under ~Y15 unclaimed.

What you expected:

The claim should not have "reset" and should properly have protected what the player had built.

Steps to reproduce:

We haven't found a way to reproduce it yet since as far as we can tell it's random. It happened in the beginning of 1.13 as well as we had just updated but then we didn't see it for months until this week. Here's a video showing it having "reset": https://youtu.be/HJjfcC6GeaE

Please paste contents of config instead of attaching file, thanks.

[RoboMWM]

thanks for edit, should prolly comment when you do so next time so issue status is updated.

[RoboMWM]

Can you provide claim file? (Paste contents.) If you can somehow get a before and after, that'd be good as well.

[MrShack]

Sorry, what do you mean with claim file?

[RoboMWM]

In ClaimData folder, there's a file for each claim.

I am also having this issue. Many of my players have reported their underground stuff randomly stolen even though they have a claim above the area.

I cannot provide a claim file because it happens entirely randomly and we have 19,896 claims.

[RoboMWM]

If there's a reliable way to reproduce this that'd help

[bigpresh]

I wonder if this happens when resizing a claim from higher up, and if so, whether it's down to the changes in PR #461 - at a quick glance, I don't see why it should be, though.

If I get a chance, I'll try that theory out.

[112RG]

Looking at that PR, it could be in how the claim is saved. Maybe something is causing saveClaim() to not save the new location
