Hi there guys! So I am trying to use this plugin (Playtime Tracker) alongside Player Rankings so that when player's reach certain Playtime required they will be given a rank. Please help thanks!

Loaded plugin PlayerRankings v3.0.2 by Ankawi
[Playtime Tracker] Still unable to find any supported reward plugins. Rewards will not be issued!​

You need to install ServerRewards or Economics

I actually figured out that this error was pointless for my case. My players still get granted ranks after playtime without using Economics or ServerRewards.
