There is s difference between PAL & NTSC. Because PAL has a significantly slower refresh rate, and thus a larger VBlank window. it has a larger safe zone, which is likely why the team didn't notice these errors themselves. However, user ZeroVolt IS seeing errors. We don't fight through a level "in a certain way" to avoid the level's graphics becoming corrupt. If this is happening, it is an issue and the only way the team can know about it is if users report it to them. We aren't going to sabotage the project by telling them. It is the only way they can know there is an issue.
