[igooch]

@tvandijck and @KiaArmani as the most recent contributors to the Unreal SDK, would you review this PR?

[zifter]

Any updates? It would be great to have it in 1.43 :)

Any updates? It would be great to have it in 1.43 :)

1.43 release is getting cut in a few hours, so it's probably too close for this release.

@zifter or @KAllan357 would you be able to test and validate the changes in this PR?

[zifter]

@igooch I'm working with @GloryOfNight in the same company and these changes are made by my request.

I actually can confirm, that it's tested, because we are using those changes currently in production.

[GloryOfNight]

We only using counter decrement. Get/Set Counter is not tested.
I'll give some time to test them to be sure.

[KiaArmani]

LGTM!

[GloryOfNight]

Tested, found issue with GetCounters() call related to default initialized content string as braces. Fixed it.
Everything looks good now.
