The mod breaks when you use invisibility potion

[NavalAce]

When you use invisibility potion the mod throws an error and all waypoints disappear.
My guess is that currently it gets your position from the online map itself and that's why everything breaks when you disappear from the online map.
I propose to instead get your own coordinates from the client, so that doesn't happen

[thebuildcraft]

It's not about your coordinates. It's about in which dimension / world you are, which for some servers, is not as simple as overworld/nether/end. It needs to find your playername in the server provided data, which is missing if you are not visible on the webmap.
Does it display an error in the chat, or only in the log file?

[NavalAce]

It does display error in the chat

[thebuildcraft]

I just released an update that prevents the error message (it was only on Dynmap servers). This is a temporary "fix" so it's less annoying until I make a more complex and reliable system to detect the current webmap dimension.

Thanks!

Also forgot to mention that it seems that waypoints don't come back on their own after invis potion runs out, so I have to relog every time that happens

[thebuildcraft]

Even after the "fix" ? When I tested it, everything came back as soon as invis ran out.
Could you please send me a log file if its really in the newest version?

[NavalAce]

Sorry, not in the newest. I'll test the newest and report

[NavalAce]

Yeah, my bad on this one. They do come back after invis runs out in the "fixed" version

[thebuildcraft]

Ok. Good 👍
Btw, I don't know yet when a real fix will come out, because it will take significantly longer than this "fix" :)

I found this workaround you talked about a year ago, but it looks like the command no longer works. Is there a way to do something similar in the current version?

[thebuildcraft]

You can try with /maplink ... and you may need to enable debug mode (make sure to disable chat logging). The thing is, these commands are just there for testing and may not even work the same for different web-maps (i.e for Bluemap vs Dynmap or even LiveAtlas). There is sadly no good way until I have time to properly fix it.

Also sorry for forgetting to answer for 3 whole weeks...
