Have you made any (noteworthy) changes to the default configuration of NCP?

I didn't change anything.

Do you run any other special plugins that affect game mechanics next to NC+ (skills, machines, adding/changing blocks, other anti-cheating)?

No

Provide additional information: for bypasses, vulnerabilities and reproducible issues, we request a debug log. Use GitHub gists or PasteBin or similar for errors and huge logs, or attach a (zip-) file here.

Concerning the speeding part, have a look at #197
The FastUse bypass is interesting: perhaps we'll need to add a check to detect fewer packets than expected...
