Client Type (ex. PC, Android, Webclient): Windows Client Version (if known. Webclient has no version.): v2.7.1 When did you first notice the bug?: With this version. Have you been able to reproduce the bug?: Yes. Information (include relevant logs, replays, screenshots): Basically, the front and back sprites for Alolan formes don't show up during battle. I know that I have seen both sprites for Alolan Marowak working, so this could be something that is somewhat intermittent, but when I tried testing this, every Alolan forme that I tried, including Alolan Marowak, was not visible.
This has already been reported, it only happens when the Alolan Pokemon is Female. Fixed with next client update
