TFS 1.X+ debugging tfs using vs debugger

[super23]

I have compiled the following server : [8.6/12X] [TFS1.3] Global + Source + Web + tools + Quest Reward System (https://otland.net/threads/8-6-12x-tfs1-3-global-source-web-tools-quest-reward-system.268391/)
But there have been random crashes and I decided to run it on the debugger and got the following stacktrace ( which I don't understand )

what is it saying exactly? and how could this be solved?

I still require help for this problem.

But use the Source in Alkurius/Alkurius-OT (https://github.com/Alkurius/Alkurius-OT) ...Because the "Quiver" needs some modifications in the source

Looks like your server has userdatas in addEvent method, which can be invalidated and creates nullpointer which then dereferenced crashes the server.
So search for any codes that use addEvent and got userdata in it and its not reconstructed.
