[2022] [BUG] All three tiers of burning effect remains active simultaneously.

All three tiers of burning effect are active all at once.

1. When ship with 2/3 burning is attacked with flamethrower, instead of refreshing it back to 1/3, it applies 1/3 in tandem with current tier.
2. During prolonged fire exchange, all 3 tiers were applied reducing both ship DPS and ship movement speed to 0. (although it could still move with ~50% speed, its reload speed in fact dropped to around 1-10% of base value)

Don't have video of this particular encounter.
Savegame was lost in time, as it was a long session. It should be easy one to recreate/investigate though.
No mods were used.
