I'm just on normal Chrome. It might've been because I had the relic that increases my number of balls, but when I went back into the game it lets me drop an extra base ball despite it having been a special one before I went to the menu.
Yeah I found the bug, quitting and resuming would clear all your relics from inventory but the effects of them persisted, good find! Working on a fix for that now and looking for other save/load bugs. Thanks for digging in!
