Anyone able to complete the server tutorial (Hilbert Hotel)?

using a custom build (GD v3.1.2 mono)

I keep getting a crash when the HilbertHotel thread function calls a method on the _HilbertHotel wrapper class

void HilbertHotel::_emit_occupy_room(uint64_t room, RID rid) {
    _HilbertHotel::get_singleton()->_occupy_room(room, rid);
}

Is this pattern of emitting signals common? I cannot find a practical example mirroring this pattern in any of the other godot servers.

Can you reproduce it if you follow the tutorial using GDScript? If not, it may be a Mono-specific bug.

Okay I was able to get it to run without mono using the same code. When I attach visual studio it seems to break in gd_mono_method.cpp

Should I take this to a github issue? I'm new here so any guidance on what I can do to help would be appreciated.

Yes, I'd say make a search on the issue tracker first, if it's already reported add a comment to it, but otherwise open a new issue.

Just in case though, search all issues not just the open ones.
