[BUG] AccessViolation when accessing the same events as CSSharp

SwiftlyS2 Version

latest

Game

Counter-Strike 2

Operating System

Linux

Bug Description

I have a CSSharp plugin that is using onTick, then I have a swiftly plugin that also uses onTick, but I get Accessviolation and the server crashes when I add the swiftly plugin as CSSharp is already using the onTick.

Would be nice if we could combine CSSharp and Swiftly here as there are a lot of CSSharp plugins I can't give up

Steps to Reproduce

1. Add a CSSharp plugin that is using onTick such as MenuManager
2. Add a swiftly plugin that also uses ontick.
3. Server crash

Expected Behavior

I would expect it not to crash.

Actual Behavior

Server crashes.

tbf, imo it's more likely that the entity is not valid at that stage
have you ever checked the validity of the entity?

I mean, if I remove CSSharp and only run the Swiftly plugin the server won't crash.
Same if I do vise-versa

strange, I'm not sure why this issue only occurs when running two plugin frameworks simultaneously

but if the entity is valid, it theoretically shouldn't cause a memory access violation

CSSharp always has weird issue on OnTick, the problem is not likely to be fixed until we figure that out. Meantime you can try adding more strict check on entities.
