I’ve read it at the time when you first posted it.
I can confirm after a long time of fishing that the fish gets away insanely more often than in Vanilla
Sounds similar to the looting bug, where mobs have empty loot windows dozens of times in a row. Hmmm.
My fishing is ~250. If im not using lure, i lose all the time even in lower level areas. I had my engineering alt make this guy a few stacks of aquadynamic fish attractors, that completely solved the problem.
