Note: As the value of variety distribution increases, the occurrences and severity of the bug decreases, except when it is set to "None."

This looks really weird, I have never seen this happen.

In 1.5, the 'more heightlevels' (MHL) patch was added. As explained in #6156 and http://www.tt-forums.net/viewtopic.php?f=33&t=72107 there are still some problems with it.
Before the 1.5 release, either the MHL patch will be removed, or it will be fixed.

In the former case, this problem would disappear by itself, since we'd go back to the situation of 1.4
In the latter case, the MHL fixes may also fix this problem. For this reason, I suggest to first wait for the fix of #6156. Perhaps after that, you can try again to see if the problem got solved as well?

In addition, I have only noticed the bug when the terrain type is set to Flat or Very flat. Otherwise, the variety distribution variable works normally. Temporary fix: set variety distribution to None when playing with terrain type set to Flat or Very Flat.

andythenorth closed the ticket.

Reason for closing: Unreproducible

Thanks for the report. Can't repro this in 1.6.1 or 1.7.1. Tried multiple combinations of height level, map size, terrain type, variety distribution, sea amount etc. No other reports of this, and it's a pretty noticeable issue when it occurs, so it's likely fixed by changes in TGP / MHL, or it's so rare that it's hard to trigger. Closing, thanks :)
