Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Dear Curators,
This patch contains bug fixes.
Tim Twice Circled
v5.1.3 Changelog
Fixed bug: game was giving 'eat or damage' warnings incorrectly for Button Polyps (heavily armored).
Fixed bug: minor issue with Species Time Trial where it would not be checked unless a new animal was added.
Fixed bug: Staff could be spawned with no skills if you started a sandbox at rank 1.
Fixed bug: Explorer trait was counting different sized backdrops of the same type as unique decorations.
Fixed bug: Backdrops could be built anywhere in larger polar domes. Also backdrops are now allowed on viewing walls of polar domes because they are deep enough that the view is not blocked.
DF 3. Sulasi: Replaced large heater with mega heater on deep outcrop tank.
UI: Squeezed a bit more horizontal pixels into the area windows can appear so you can have 3 staff windows + the staff management window open at the same time (16:9 aspect ratio).
Modding: Made staff item allow/disallow/prioritise grid scroll if it gets too long due to additional items being added in mods. The value when this starts to scroll can be edited in gui.data: staffItemGridMaxHeight via a mod if desired.
