6574        corrects the behaviour when a custom element changes to another custom
6575        element with a higher element number that has change actions defined.
6576        Normally, only one change per frame is allowed for custom elements.
6577        Therefore, it is checked if a custom element already changed in the
6578        current frame; if it did, subsequent changes are suppressed.
6579        Unfortunately, this is only checked for element changes, but not for
6580        change actions, which are still executed. As the function above loops
6581        through all custom elements from lower to higher, an element change
6582        resulting in a lower CE number won't be checked again, while a target
6583        element with a higher number will also be checked, and potential change
6584        actions will get executed for this CE, too (which is wrong), while
6585        further changes are ignored (which is correct). As this bugfix breaks
6586        Zelda II (and introduces graphical bugs to Zelda I, and also breaks a
6587        few other levels like Alan Bond's "FMV"), allow the previous, incorrect
