Here are a few bugs that were spotted when playing with my patchpack by Moriarty, I have checked with your clean patch bumped to trunk and can confirm them.
While bumping I had to only remove the "true" from the one conflicting line to keep your patch going. (r20240 at time of writing.)
Some of these bugs might probably already be known by you judging by the first post, anyway here they are.
a) The "- Measurement tool" has issues. If you click and do NOT drag but just hold the mouse in place, it starts randomly flickering through numbers for manhatten distances and "bird fly distance".
b) The measurement tool also shows the results of the last measurement if you click but don't drag. Surely it should start with NO results.
Also I noticed a few other things when testing.
- If you have just generated a map and you use the measurement tool on one tile the height from sea sometimes give some weird results. eg. height = 32 meters while the height difference per tile is 50 meters ... very strange.
- Also when measuring on a flat piece of land the height difference is always reported as "50 meters" or "-50 meters" but never 0, except if you have just started the game then it reports 0 meters as it should.
Also attached a screenshot that displays the weird behaviour mentioned above, it is taken while selecting 1 tile and holding it there.
Another little bug reported by thetzar.
The "R" shortcut is already used for the removal tool and will prevent the removal tool to be selected by means of the shortcut.
Please ignore, if this is not the case in your clean patch as I have not yet tested this ...
