It's a mumble bug, we call it the "demon" :D
Haven't found a solution yet though, might try #9.

Open huditemeffectmeter_killstreak.
Set visible/wide to 0 in "ItemEffectMeterLabel".
Change xpos/ypos in "ItemEffectMeterCount" and "ItemEffectMeterCount2".
Maybe extend the "HudItemEffectMeter" frame if the number disappears.

Not sure if this helps though if you don't know basic stuff like that yet.

Version 3.44
* Added PVhud style TargetID health.
* Changed file hoster.
* Made the buff shadow black by default.

Modified files: clientscheme.res, spectatorguihealth.res, targetid.res

Definitely m0rehud.

broeselhud_blue is fully updated and slightly edited. It uses the HP cross by default though, so you might have to follow FAQ #3.

I fixed the 0s cutting off like that (it's a tiny change in clientscheme.res), just for your information.

Take your HUD the way it is or learn some basic HUD editing. There's a few tutorials out there. If somebody tells you how to do something and you still can't implement it, maybe don't make requests for now.

This HUD is optimised for 1680x1050. Sure there's a few things here and there that are sligthly off (see FAQ #4 and #5 for example) but overall it works well at lower resolutions.

Add this to your resource/ui/hudmediccharge.res below the "ChargeLabel" section:

"ChargeLabelSmall"
{
"ControlName" "CExLabel"
"fieldName" "ChargeLabelSmall"
"xpos" "c-50"
"ypos" "c104"
"zpos" "3"
"wide" "100"
"tall" "15"
"autoResize" "1"
"pinCorner" "2"
"visible" "1"
"enabled" "1"
"tabPosition" "0"
"labelText" "#TF_UberchargeMinHUD"
"textAlignment" "center"
"dulltext" "0"
"brighttext" "0"
"fgcolor" "0 0 0 255"
"font" "surface16"
}

Edit: You're welcome. Let me just explain that this is not in the HUD by default because it doesn't work with the Vaccinator.

Version 3.43
* Added/updated screenshots in the start post.

Modified files: clientscheme.res, hudplayerhealth_numeric.res

Version 3.42

I know what you mean, this is perfectly normal though. You can follow FAQ #4 and see if it improves (which you already did) but in the end it can't be 100% centered due to the way HUDs are made in TF2.

Maybe give me some information? Resolution, screenshots, what have you tried?
