I was spawning some blueprings in creative

any steps to reproduce?

[Fank]

nope, was just spaming different blueprints in creative. Were testing something something, so i needed to disable the plugin. Only have 1 server running right now, so im unable to find reproduction steps for it.

I've also gotten this bug, just crashed my server. If I have time today I'll look at the code.

[SplenectomY]

I did a very quick look, In PBData.cs you have long pbOwner = tracker.PB.OwnerId; at line 57. This might need a null check for the .PB in case the programming block is removed from the server or something else. Just a if(tracker.PB != null) continue; right before that line might solve the issue, or at least stop the crashes.

[sirhamsteralot]

hmm i think that might be it actually tho i dont see how PB could ever be null

E: ill throw in the nullcheck for it anyways, its a good thing to have

[SplenectomY]

I thought the same thing, but I don't really know what else it could be. I'll look a little deeper once I can, but that's probably the only thing in there that could ever possibly be a null object.

[sirhamsteralot]

actually nvm i think i see it, the ownerName string is prolly null

[sirhamsteralot]

possibly fixed in commit a9b1bcd

pushing hotfix soon

[sirhamsteralot]

Possibly fixed in version v1.0.3.13

[SplenectomY]

Aha. Yeah you're probably right, considering the identity check runs this this.m_allIdentities.TryGetValue(identityId, out result); and if it doens't find it, there's no default value in TryGetIdentity(). It would just return null.

[SplenectomY]

Bad news, the latest version didn't fix the issue.

[sirhamsteralot]

if anyone has a minidump for this id really appreciate it

[sirhamsteralot]

you can try this release in the meantime, it has debug symbols turned on and a trycatch around the suspected area which should swallow the exception :( release

[sirhamsteralot]

could you try using this and seeing if it gives a better stacktrace? i refactored some bits so it should. HaE_PBLimiter.zip

[sirhamsteralot]

Note to self: might be a correlation to EEM

[sirhamsteralot]

Im going to close this issue as it seems to have been fixed in one of the newest plugin releases. removed the warning on startup in the newest release and pushed to stable.
