I am using the nightly build repo under ubuntu. Since yesterday, Dec 13 2021, the following bug appears:
Whenever I try to place coaster, I am shown the window where one may choose an existing design, then immediately the game freezes and the game window is gone.
When I start the game in the console, I get the following error:
openrct2 $ openrct2: /build/openrct2-IU8I58/openrct2-0.3.5.1-develop-0~3020-202112132017/src/openrct2/drawing/Drawing.cpp:70: uint8_t PaletteMap::Blend(uint8_t, uint8_t) const: Zusicherung >>src != 0 && (src - 1) < _numMaps<< nicht erf?llt.
Abgebrochen (Speicherabzug geschrieben)
(The latter is German for "Aborted (memory dump written)")
Interestingly this issue does not occur when I play a flat ride or a transport ride.
