No major release is without quirks. The community has identified three specific bugs unique to v1.20.25.
In the Traits tab, you can now use evaluated parameters. For example, setting a weapon's ATK formula to (a.level * 1.5) + (a.agi / 2) behaves dynamically, updating every turn without a separate plugin.
As 4K monitors become standard, older versions of RPG Maker often struggled with scaling, resulting in blurry fonts or jittery pixel art on high-DPI screens. The 1.20.25 update introduced refinements to how the engine handles window resizing and fullscreen scaling, ensuring that pixel art remains crisp and UI elements remain legible on modern displays.
Symptom: When using "Action Sequences 3," character sprites leave transparent trails.
Workaround: In the RPG Maker Plugin 1.20.25 battle settings, set Sprite Cache Limit to 4 (down from the default of 8). This forces garbage collection after each action.
Plugin 1.20.25 is a maintenance release focused on reliability, compatibility, and small performance gains. It’s safe and generally beneficial to adopt, provided you back up projects and test event-heavy and plugin-heavy areas of your game.
