[Bug]: NPE crashes server when breeding Sniffers

ByThePowerOfScience opened this issue · 3 comments

What happened?

Just needs a null check in that method.

Also, try to avoid putting actual logic inside Mixin methods, since those can't be soft-patched by other devs for compatibility or bug fixes. Best practice is to make your Mixin just call another method outside of the protected mixin folder, so the logic can be transformed if needed. (Because if someone needs to transform it, there's definitely a reason.)

Stacktrace:

Additional context

I'm using a mod that augments how Sniffers behave (Snifferent), so that's probably triggering the exception, but it's just an NPE and it's happening inside RMS's mixin which isn't too hard to patch.

Before submitting

  • I tested that the problem is caused by this mod (the bug does not happen when removing this mod)
  • I checked that there are no similar posts (open or closed) related to the this problem

Wait, the source is already checking null there. What the heck?

commented

Oh you patched it after the current release. Nevermind, issue closed.

commented

Correct, fixed inside the sourcecode, but not yet released.
But thanks for reporting anyways 👍
