KSP Version 0.1.1.0
Build ID: 10752762
OS: Windows 11
CPU/GPU shouldn't matter: i7-10700K / RTX3090
Description:
J-X4 Whiplash , air breathing , methane engine (bug might persist on similar engine) do not restart after air deprivation. Still consume fuels.
update edit: any air breathing engines.
Steps to Replicate:
1. Make craft that has methane only, no oxygen.
2. Use only J-X4 engines (more than one air breathing engines)
3. Climb up at maximum speed until high enough for not enough air (engine status will say methane air deprive?)
4. Throttle at 0%
5. Dive back to low altitude (showing "air" resources half way, throttle to 100%
6. Engine status "nominal" , but no thrust. methane is drained.
Can't find workaround yet. manually "deactivate/reactivate" doesn't work. restage the engine and trigger stage doesn't work.
EDIT, workaround found: Problem is not with the air-breathing engines, but on the air intake components do not provide "AIR" to engines other than the "first" air breathing engines.
Temporary work around is toggling the air input components to disable/enable air intake.
NO MOD, 100% unmodified
Screenshot showing the engine not producing power , throttle at 82% (tested repeatedly from 0% to 100%)
