Just got this Travel System error when logging in this morning.

Something about a map node count mismatch.

Zygor Guides Viewer: WARNING: Travel system reports map node count mismatch. Faction A, 2627 nodes present, 2625 expected.
Zygor Guides Viewer: Please file a bug report with the above message. You might want to disable the Travel System temporarily, as it's unstable now. We're sorry about that.

I already reported it in this thread:
http://zygorguides.com/forum/showthr...in-guide-14630

I did not notice any further issues with it so far though.
I think it's related to this change so maybe it affects only paths across this zone border:

Travel: Added another Azsuna/Suramar ground crossing to travel system data.
