When you do reload pex via command the temporary permission (not group) resets too. players looses temporary perms when plugin is reloaded

Please save the temporary permission to file/sql

make main groups and subgroups

• main group is priority on prefixes
• subgroup you will only inherit the permission not the prefix

when adding a group to a player (not group set) the player looses the default group permission

• work around is add the default inheritance to the sub group

These are all intentional design decisions in PEX 1.x. The first issue can be worked around by setting permissions on a group, then adding that group as a temporary group.

The second issue will hopefully be resolved in PEX 2.0 with more flexible weight handling.

The last issue is resolved in PEX 2.0: the default group is always applied to users
