+ Summary of bugfix:
+ Fixed property "can fall" for run-time element "EL_AMOEBA_DROPPING"
+
+ Bug was introduced in version:
+ 2.0.1
+
+ Bug was fixed in version:
+ 4.1.4.2
+
+ Description:
+ In version 2.0.1, a new run-time element "EL_AMOEBA_DROPPING" was added,
+ but the property "can fall" was missing, which caused some levels to be
+ unsolvable. This was fixed in version 4.1.4.2.
+
+ Affected levels/tapes:
+ An example for a tape that was fixed by this bugfix is tape 029 from the
+ level set "rnd_sam_bateman".
+ The wrong behaviour will still be used for all levels or tapes that were
+ created/recorded with it. An example for this is tape 023 from the level
+ set "rnd_gerhard_haeusler", which was recorded with a buggy game engine.

+ Summary of bugfix/change:
+ Fixed move speed of elements entering or leaving magic wall.
+
+ Fixed/changed in version:
+ 2.0.1
+
+ Description:
+ Before 2.0.1, move speed of elements entering or leaving magic wall was
+ twice as fast as it is now.
+ Since 2.0.1, this is set to a lower value by using move_stepsize_list[].
+
+ Affected levels/tapes:
+ The first condition is generally needed for all levels/tapes before version
+ 2.0.1, which might use the old behaviour before it was changed; known tapes
+ that are affected: Tape 014 from the level set "rnd_conor_mancone".
+ The second condition is an exception from the above case and is needed for
+ the special case of tapes recorded with game (not engine!) version 2.0.1 or
+ above, but before it was known that this change would break tapes like the
+ above and was fixed in 4.1.4.2, so that the changed behaviour was active
+ although the engine version while recording maybe was before 2.0.1. There
+ are a lot of tapes that are affected by this exception, like tape 006 from
+ the level set "rnd_conor_mancone".
