A funny bug in v1.0.3: When loading a savefile in progress of Virus Fortress, the normal stage select screen appears, and it goes to nowhere after choosing the fortress (like entering the select screen again).
No, it doesn't work.
I give you more details about this bug I faced:
The save file is in progress of Virus Fortress 2, saved in v1.0.2 where the invisible wall happened. In v1.0.3, it displays Dual W fortress which should not be accessible at this moment; if I click the Dual W fortress, it "returns" to select screen; if I switch to Virus Fortress correctly and click it, the game freezes with black screen and never proceeds to Virus Fortress.
I tried to save in another slot and load it, as well as enter a normal stage and exit, but none of them fixes the bug.
