+       corrects the behaviour when a custom element changes to another custom
+       element with a higher element number that has change actions defined.
+       Normally, only one change per frame is allowed for custom elements.
+       Therefore, it is checked if a custom element already changed in the
+       current frame; if it did, subsequent changes are suppressed.
+       Unfortunately, this is only checked for element changes, but not for
+       change actions, which are still executed. As the function above loops
+       through all custom elements from lower to higher, an element change
+       resulting in a lower CE number won't be checked again, while a target
+       element with a higher number will also be checked, and potential change
+       actions will get executed for this CE, too (which is wrong), while
+       further changes are ignored (which is correct). As this bugfix breaks
+       Zelda II (and introduces graphical bugs to Zelda I, and also breaks a
