## Round ID
34815

## Description of the bug
if I had to guess, the fire from this chem is setting the fire to an alpha of 34 instead of staying at 255, which makes people "invisible". I will list the properties of the chem now, and include an image below.
Neuroshielding Level 1
Anti-parasitic Level 3
Pneumotoxic Level 1
Hypometabolic Level 6
Oxidizing Level 3
Viscous Level 1
Alcoholic Level 5

## What's the difference with what should have happened?
fire should not be making anything (including mobs) invisible.

## How do we reproduce this bug?
1. get a weird chem
2. the fire within has a weird alpha that makes people invisible.

## Attached logs
```
N/A
```

Start by reproducing round 34815 with the listed chem properties and observe the fire effect on mobs. Trace where that fire's alpha is set, then verify that affected mobs and other fire objects remain visible rather than becoming invisible.
