Does the issue occur in the editor or during gameplay?
Gameplay

If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
Free-movement third-person

Briefly describe the issue you're experiencing:
Entities stays in white flash texture after being hit several times with weapon which cooldown is lower than 1

Are there any errors in the in-game debug console or external console window?
No

Provide the steps necessary to reproduce the issue:
Make a weapon with cooldown that is lower than 1, better to lower it as much as possible, but on 0.6 is already observable. Hit an entity several times

Provide a download link to the bare bones project (strongly recommended if it's an in-game issue, since this helps significantly when attempting to reproduce it; the report will also be given more priority in this case):

You can disable the flash effect if it's causing issues.

The common cause for the flash being stuck is with animations on NPC's and player.
It usually occurs when not all the base animations are implemented (idle, walk, death, attack etc) with at least 3+ frames for things like attack and death.

But if it's unresolvable, you can also just disable the effect entirely.

    Slayer I've found that the only animation that causes this bug is the "death" one, adding one will solve this issue, when having shake/flash on.
