When directly installing SD 1.2 on Unity 6.4 (6000.4.7f1) and Unity 6.5, the icons fail to display.Installing the older SD 1.0 on Unity 6.4 (6000.4.7f1) shows icons normally. After overwriting it with SD 1.2 via replacement installation, the icons still appear, but errors occur once the project restarts. It seems there are issues when updating the plugin through file replacement.
There may have been an error replacing a certain DLL during the overwrite process. Even so, it’s confirmed that version 1.2 causes missing icon issues, and BDP may suffer from the same problem.
