JPEXS Free Flash Decompiler Issue Tracker

> What steps will reproduce the problem? 1. Open the attached SWF in FFdec. 2. Click the "Rename invalid identifiers" button. 3. Save the modified SWF and open it in Flash Player. 4. Select the Runner character on the game's main menu. 5. Press the spacebar to start level 1. > What is the expected output? What do you see instead? I expect the modified SWF file to function the same way as the original. Instead, the levels are changed and the game becomes unplayable. > What version of the product are you using? Is it "nightly build"? Which operating system do you have? FFdec version: 18.3.3 nightly build 2444 Operating system: Windows 10 64-bit > Please provide any additional information below. If the problem is related to a SWF file, attach it here, otherwise we can't help you. I read the warning that Rename Invalid Identifiers can damage the SWF, but I still want to report this in case it helps improve FFdec. I've attached the original SWF file below, along with screenshots of level 1 in the original and modified SWF files. Renaming identifiers should not change the levels.
