Thank you thank you! XD
The only mod I've got enabled that directly affects Bowtorn in any way is Darce's Drifters Redone, but that only alters their textures (that I know of). Just to be sure, I removed it from the server but it didn't seem to change their behavior. I compared the bowtorn.json file on the server with that of a vanilla server build, but there weren't any differences there. Played around a bit with the variables in the JSON file just to see if I could possibly make them completely docile or zero out the damage they deal, but also didn't seem to change anything...which I found odd because it should've. For now, I've just disabled them entirely by renaming the JSON file while I test mods on a separate server build to narrow down which ones might be causing the issue.
