I cant see the fishing rod quest!(when I click it, only the wart quest comes up and not the fishing rod one.)
Also the zombie killing quest is hidden.( when i click it, the zombie quest opens only, not the one for green antimatter.)
the arrows are all messed up.
I do not know what is causing the issue. I tried changing the GUI scale, Zoom in/out, Change game window size. Nothing works. Using the latest Beta version on curseforge.

It looks like you are using a very outdated version. The most recent version is a release version released on May 20, 2020. You are probably using the beta version released on May 17, 2019. Your version is 35 versions out-of-date
