This might be a duplicate, or I am completely shooting in the weeds here, however - I received a report today where a player was placing and picking up buildable's and receiving XP each time.

Put down door +5xp
Pickup door

Pickup door

It is the same door being placed in the same position over and over again.  I briefly checked plugin code and it seems between line 8661:8667 is where the XP for placing buildable is granted and no other check but the cooldown is performed.

if (config.xpBuilding.buildxpdelay && (GetPlayerCooldown(player.userID, "build") != 0))
    {
        _buildCooldowns[player.userID] = CurrentTime + config.xpBuilding.buildxpdelayseconds;
        allowxp = false;
    }
_buildCooldowns[player.userID] = CurrentTime + config.xpBuilding.buildxpdelayseconds;
if (allowxp) GainExp(player, addxp);​

the cooldown is there for that reason and say you set it to 10 seconds the time they spend trying to use this as some sort of exploit isn't actually helping them as there are much easier ways to gain more xp than trying this

So, over-reacting.  That is fair and standard for me 😂 ... I will add a cooldown of 10 secs and listen for updates from my pop.  Thanks a ton for replying so fast.

Edit to add: Great plugin - thanks so much for creating this.
