@ -52,6 +52,8 @@ changelog.txt uses a syntax similar to RST, with a few special sequences:
- `embark-assistant`:
- fixed bug causing crash on worlds without generated metals (as well as pruning vectors as originally intended).
- fixed bug causing mineral matching to fail to cut off at the magma sea, reporting presence of things that aren't (like DF does currently).
- fixed bug causing half of the river tiles not to be recognized.
- added logic to detect some river tiles DF doesn't generate data for (but are definitely present).
- `gui/autogems`: fixed error when no world is loaded
- `gui/companion-order`:
- fixed error when resetting group leaders

// This is messy. DF has some weird logic to leave out river bends with a South and an East connection, as well
// as river sources (and presumably sinks) that are to the North or the West of the connecting river.
// Experiments indicate these implicit river bends inherit their River Elevation from the lower of the two
// "parents", and it's assumed river sources and sinks similarly inherit it from their sole "parent".
// Two issues are known:
// - Lake and Ocean tiles may be marked as having a river when DF doesn't. However, DF does allow for rivers to
// exist in Ocean/Lake tiles, as well as sources/sinks.
// - DF generates rivers on/under glaciers, but does not display them (as they're frozen), nor are their names
// displayed.
