Description of the bug

https://youtu.be/X8sUONx9-Q8?si=cWiWQdG9PZNsR45A

Oddity occurs once at :40

https://youtu.be/4QL1hHQejHw

Happened some more late on twice in a row- seems kinda random but maybe it's a rounding error or something with the amount of fuel left inside the canister.

What's the difference with what should have happened?

Shoulda been oxygen fire only

How do we reproduce this bug?

1. Fill incin tanks with oxygen
2. Cycle through the various u/t amounts
3. Seemingly randomly it may put out regular incinerator fire
   ...

Issue Bingo

• Issue could be reproduced at least once
• Issue happened in a recent (less than 7 days ago) round
• Couldn't find an existing issue about this (https://github.com/cmss13-devs/cmss13/issues)

i have no idea how liquid work on the floor on the floor but that seem that's what's causing the weirdness there....

first video i can see you fire upon a grease spot maybe you have heated up it enough that it then catch fire?

second video we clearly see you using you extinguisher (leaving water on the floor) that would explain why they extinguish faster
then the two orange flame are weird could be chemical we can't see that you manage to light up like in first video...

It seems random- I assume it's to do with X amount of fuel left in the canister if I had to guess or perhaps because I set it to 7 u/ts while the canister had 70%? While I can get it to repeat the oddity I can't consistently get it to repeat. AFAIK liquids on the ground are hard coded not to ignite- at least the last time I tried with welding fuel I couldn't.

tested it out and could reproduce it by using a custom fuel tank m240a1 and filling it with oxygen after a few spray it made some red flames.. when i examine it on local that's what i got.

apparently it fire napalm at random when starting as oxygen.
