Details

Description
Have attempted to cooldown the essentials repair feature using both regex and plain text settings in command-cooldowns. Have checked ess debug and verified that essentials does not even verify if the user has the permission essentials.commandcooldowns.bypass when the user uses the repair command... all it checks is if they have the essentials.repair permission and so always runs the command regardless of now many times per second they choose to run it.

Steps to reproduce
Attempt to apply cooldown to /repair, /repair all, /fix, /fix all... any combination of the above... then try to run any of those commands as many times as you like in however short of a time as you'd like.

Expected behavior
Command should either obey command-cooldowns or repair/repair all will need its own cooldown like heal/feed gets.

Screenshots

It looks like you're defining your cooldowns incorrectly. The correct format is as follows:

command-cooldowns:
  repair: 43200

not as above:

command-cooldowns:
  - '^(fix|repair)( all)?': 43200
  - fix: 43200
  - repair: 43200

Note the lack of a - before the definition in the correct format. The command-cooldowns section isn't a list, but rather a parent node. The removal of the - and preceding space from your definitions should hopefully solve your issue.

Extra: proof of the cooldown function working correctly with the fixed format:

[08:43:30 INFO]: ExplodingGravy issued server command: /repair
[08:43:30 INFO]: [Essentials] checking if ExplodingGravy has essentials.commandcooldowns.bypass - false
[08:43:30 INFO]: [Essentials] Checking command 'repair' against cooldown 'repair( .*)?': true
[08:43:30 INFO]: [Essentials] Applying 43200000ms cooldown on /repair for ExplodingGravy.

thanks for that i'd never have seen the issue.
