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.
