This update is related to v1.12.2 and v1.13.2.
1.14.4 users do not need to update, tho it is still adviced.

* An update in 1.14.4 renamed a package for no reason to "craftbukkit" making it unable to work on 1.12 and 1.13 since this import does not exist prior to 1.14's release... Fixed this by using a different import which works on all 3 versions.
* Fixed classnotfound/imports on tag sections of which classes did not exist(my mistake).
Specifically tier and rank item creations.
* The update checker didnt work for these versions for the same sake as point 1...
* Changed api-version from 1.14 to 1.13 so it works on all versions.

Please note: Currently AdvancedBCRanks only works on the latest of:
- 1.12(1.12.2)
- 1.13(1.13.2)
- 1.14(1.14.4)

1.9-1.11 May be supported in a future update, however sub versions(i.e 1.14.1-2-3) will never be supported.
