Hmmm; ok, I noticed that the sdktools.ext.dll file found within the auto.2.ep2 folder within the extensions folder wasn't as current as the rest of the files, which would lead me to believe that, when I updated the rest of the files, this one was left unchanged for some reason, which would result in the SDK Tools appearing as v1.0.4 instead of 1.1.0...am I correct in this assumption? I'm going to try uploading the new file again to see if this is the case. If so, then thank you for helping me to find the problem!

It's part of the SM 1.1 package, you just have to extract it and upload
the content of it's folder "addons\sourcemod\extensions\"
to the corresponding folder on your gameserver "orangebox\dod\addons\sourcemod\extension s\"
and overwrite all existing files. - Preferably while the gameserver is switched off.

After that start up your gameserver and check with "meta list" again
and it should say "SDK Tools (1.1.0-dev) by AlliedModders LLC".

Let me know once it works
