@ljacqu Will it be fixed?

ljacqu commented 4 years ago

Yes, we'll need to fix it. Thanks for reporting this!

sgdc3 commented 4 years ago

@radek203 can you please try to replicate the issue using the latest dev build?

radek203 commented 4 years ago

@sgdc3 I don't know how it was created, I can only say that a lot of people wanted to enter the server and I manually turned off the protective antibot by command.

ljacqu commented 4 years ago

Yes, it's a bug on our side. From the code it's quite apparent that it's not thread safe, not to mention that we haven't touched the antibot feature since 2018...

sgdc3 commented 4 years ago

@ljacqu I fixed the issue in #1992
