Is this mod works only for SevTech: Ages?

i'm not a programmer.
comparing ecompiled-code with JourneyMapStages released on Mar 4, 2019:

 final EntityPlayer player = (EntityPlayer)Minecraft.func_71410_x().field_71439_g;
 final PlayerDataHandler.IStageData stages = PlayerDataHandler.getStageData(player);

the code of WailaStages released on May 2, 2018 :

final PlayerDataHandler.IStageData stageData = PlayerDataHandler.getStageData(PlayerUtils.getClientPlayer());

i think a update is needed

crash log：

I just set up a test pack and can confirm this mod works as expected using the latest recommended release of each dependency.

• Bookshelf 2.3.590
• CraftTweaker 4.1.20.680
• Game Stages 2.0.123
• Hwyla 1.8.26-B41
• Waila Stages 2.0.24

This mod is not limited to SevTech ages and can be used in other packs as long as you follow the license.
