Spam your mod in the log file

Hello! I had a problem with one of the other mods that I reported to the modder with the log file attached. According to his fashion, he is now working, and according to your fashion, he asked me to inform you that your mod is causing a lot of spam in the log file. I provide you with a link to our communication so as not to create unnecessary reports. If I'm needed, I'm available. Thank you!

Thank you for reporting, I will look into this.

Hi there, I'm the dev from the other issue (unrelated problem btw). Since I realize the log is quite long, this is the error I was referring to:

It occurs during the AttachCapabilitiesEvent for entities and thus gets printed every time an entity is created.

Thanks for the information. I will add a simple null check. I assume event.getObject() can be null and not the event itself.
