In your log you first used the regular profile which does not equip Tentacle Hat, Ephemeral Fishing Pole and Worm Surpreme, I saw it throw the fish and kill the mob and move back to start fishing again, so I do not see any issue here. Then in the second part of your log you loaded the BETA profile which should use Worm Surpreme, Tentacle Hat and the Ephemeral Fishing Pole. I noticed it did equip your Tentacle Hat, same as your worm surpreme. When you had the minnow, it equipped back your regular head item, and used the fish, killed it. Then it moved back to the fishing location and equipped your Tentacle Hat again, same as your worm surpreme. So this seems to work as intented. I did notice it did not attempt to equip Ephemeral Fishing Pole, did you had one in your bags while using the profile ? If not, the profile is fine, if you did had one I will have to recheck the profile. Your issue with your pet killing the mob and unable to loot has come up before, disable in Singular the use of your pets, that should fix the issue.
