LMP server issue

[space-shoop]

Hi everyone! This is my first time on the forums so I'm not sure if I'm supposed to post this issue here (please tell me if this is the incorrect channel).

So, as of recently, I have had issues with Luna Multiplayer (LMP), usually after a couple months of using the server (hosted locally on my computer and downloaded from here). This has happened twice now, with the 1st one resulting in a complete re-download of the LMP server and removal of all progress.

Here is the transcript:

[21:05:44][Fatal]: Error in main server thread, Exception: System.InvalidOperationException: Sequence contains no elements
   at System.Linq.ThrowHelper.ThrowNoElementsException()
   at System.Linq.Enumerable.First[TSource](IEnumerable`1 source)
   at Server.System.Vessel.Classes.Vessel..ctor(ConfigNode cfgNode) in C:\projects\lunamultiplayer\Server\System\Vessel\Classes\Vessel.cs:line 26
   at Server.System.VesselStoreSystem.LoadExistingVessels() in C:\projects\lunamultiplayer\Server\System\VesselStoreSystem.cs:line 62
   at Server.MainServer.Main() in C:\projects\lunamultiplayer\Server\MainServer.cs:line 80

I do not know the exact sequence of events, however I can give you general information:
A couple days before the issue, I installed and uninstalled TAC life support, which left my ship in shambles (manoeuvre nodes were incorrectly placed, resources that weren't put into the craft like oxygen, CO2, wastewater, water, etc.), but seemed to be fixed after I closed the server and the client and reopened both.

A couple minutes before the issue, I was burning my engine and it kept shutting off for no reason, as if it was lagging, and it was jittering around suddenly. After at least 3-4 times of this, the server gave up and crashed.

I found the issue! It is because you either CHANGED a file, or a file is EMPTY. To find this, if you're on windows, and you have have this issue, go into the LMP server file and search  ".txt size:empty". Then delete that file, and it should do the trick!
