Hi, asked in Discord and not sure if Shinies are needed or not.
Anyway trying to complete the fishing Log I have caught all 14 of the shellos including the 2 normal ones and my total goes up to 87.5% this has been raising about 6% each new catch so with both shiny versions this would then equal 100% (although if that is the case getting both shiny versions is evil.)
However for Clobbopus I have caught all apart from the yellow ringed so far and my total is on 72.7% this is rising by 9% each time so even with the yellow ring and the shiny version this will only total 91% indicating that one is missing.
Thanks

Thank you for posting, I was able to reproduce this bug in the latest version.

Hi there! We're currently going through older tickets, and I've found that this issues has continued into our current version (8.3.6); there is no entry for #10 in the game, so the log cannot be completed. As such, I'll go ahead and move this to internal! Thank you!
