Let it be known that after careful consideration, a previously undisclosed
'hard' height cap has been removed from ships in regards to maximum lift
power.

What does this mean?

Ships now have the capability to travel over any type of terrain, given enough
(which may be considerable) lift power. This means class 3's over heavy forest
and mountains, class 4 over mountains etc.

However, it is to be importantly noted that at this point, the newly imposed
'soft' cap is subject to change and tuning, with or without notice.
