so this may not be a major bug, seeing that it is almost a frame perfect glitch, but if you are about to be hit as wortox, you drop a soul down on almost the exact frame as you are getting hit. i experienced this in a public klei official server while down in the ruins. I am generally confused at why this happens
1: you fight an enemy that only hits once every now and then (bishop / knight recommended)
2: you wait for the attack animation to start
3: you drop a soul before you get hit (it works sometimes)
4: congrats! you found the bug, its not game breaking seeing that many bosses / enemies hit multiple times, but its weird none the less.
