New update changed the config structure which forced me to use a default config when launching after the update
Using textcompare to compare the configs shows me that the only new entries are in the flip cancel section.
Fix:
Head to C:\Users\[name]\AppData\Roaming\GamingOnSteroids\RL / %appdata%
Open the backup INI that was generated and replace the flip cancels section with this
[Flip Cancels] Enable = true Automatic Flip Cancellation = false Use Old Version = true Cancel On Front Diagonal Flips = true Cancel On Backward Diagonal Flips = false Cancel On Backward Flips = true Automatic Flip Cancellation Distance = 500.000000 Automatic Flip Cancellation Time = true Flip Cancellation Time = 0.800000 Speed Flip Hotkey = 67
And delete this entry from [AERIAL BOT BETA]:
Use New Aerial Controls = true
Now delete the new config and rename RLSettings.ini_backup to RLSettings.ini
Now your config is updated.
Hope this helps somebody, new update looks interesting
If the tool breaks your config again you can use this tool to compare to see how to fix yours
