Teleport in graphical glitch

[SpenceLack]

It has been noted that If you place a unit and then immediately after make it animate the post_teleport animation, there’s a frame of the unit fully-visible before the animation begins. This occurs even in official campaigns like scenario 15 of Eastern Invasion.

Nothing will show in the game logs as this is a graphical glitch, not a crash.
Easiest way to see it is to play Eastern Invasion, use debug mode to skip to level 15, and pay attention to the silver mage Mefel when he teleports in. Probably best to turn off accelerated movement in Preferences as well, as that makes the glitch harder to see.

I think that bug has been around for a while - I believe that it's the bug being discussed in this topic.

I made a video and slowed it down so that it's easy to see the issue.

Hi,
There's a really ugly hack that might help or at least give you more ideas: create a unit with a teleport in recruit anim?

Cheers!

Oh, if it has already been reported then disregard, I guess.

Spannerbag, yes I did find that forum post and it works to fix the problem! I used that clever solution to resolve the issue in my UMC.

Glad it helped!
Cheers!
