[MorkaZ]

Parsing text to enchantment does not work (tested with newest spigot).
Example:
set {_test} to "sharpness 2" parsed as enchantment
enchant player's tool with {_test}

Effect:
Player's tool is not enchanted. Skript did nothing.

[MorkaZ]

formating slot in current inventory is formating effects also in player's inventory up from 2 row.

[MorkaZ]

Operations on regions is not working at 80% with Worldguard 6.0+
Also, checking that player is an owner of region, when regions are set in list variable is not working propetly in worlguard 5 +. Checked also in older spigot versions and newests. Same result.
