Track corrupted after reload in route planner: waypoints longitude changed

Hi,

I'm currently planning my HRP trip for this summer, and evaluating Locus Map, which seemed to me the most complete and performant app available these days.

So, I started creating a route yesterday with the web app, adding multiple waypoints, moving a few, etc. I saved my track a few times, overwriting it. Made some change today, saved again. Then reloaded it a few minutes later in the route planner. And boom, the track has been corrupted, with a dozen waypoints moved from their location to some random longitude. Looks like waypoints latitude is still correct, though.

I tried to move the waypoints back to their original position, but it totally messed the track up by linking the waypoints to the last one.

See attached files, showing view after track reload and after moving the waypoints back in place.

Is this a known problem? Can I get my healthy track back? I mean, is there some track history somewhere in the filesystem?

I need to know if this app is reliable before I commit too much.

Thanks in advance!
And congrats for the good work so far :-)
