Vgstation13: Xray gun causes turf sprite corruption for entire z-levels when fired

[BobdaBiscuit]

Description of issue

When an xray gun is shot it leaves a burn mark through every turf the laser hits, over time these burn marks (or more commonly, every turf that DOESN'T have a burn mark) has it's sprite fucked.

Sprites occasionally change what they are, so it can go from black, to a potion, to a wraith, and rather entertainingly a plasma hotspot.

Difference between expected and actual behavior

Expected

• Warning shot valids secure with bullet holes throughout the station

Actual

• Entire z-level is visibly fucked

Steps to reproduce

The issue itself takes time to manifest but the following worked for quickly getting it to happen.

• Get 2 xray guns and shoot up the main station
• Move to the asteroid and shoot up there
• Return to station
• Station turfs are missing sprites

Specific information for locating

N/A

Length of time in which bug has been known to occur

Since the X-ray gun got added.

Fucking _AMAZING_

I've noticed space tiles do this on occasion, like all the pieces of space dust will become ethereal goliaths or waffles or emags or something. I don't know if it's related at all but BYOND is simply wonderful

It's a known BYOND bug
It's clientside; relogging will temporarily fix it

However, the x-ray laser causing it to happen more frequently is interesting. Maybe we can finally track down the cause!
