## [4.1.4](https://github.com/mob-sakai/ParticleEffectForUGUI/compare/4.1.3...4.1.4) (2022-07-01)

### Bug Fixes

* add `Enabled` toggle in overlay window ([f97e619](f97e6195e6))
* if `m_Particles` contains null, an error will occur ([550d0c4](550d0c43be)), closes [#214](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/214)
* ParticleSystem reordering and refreshing in inspector does not work for prefab asset ([7eb4112](7eb41124db))
* refresh button does not works in prefab edit mode ([c1538a8](c1538a8399)), closes [#214](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/214)
* when `UIParticlrRenderer` destroy manually, an error will occur ([a11d2d0](a11d2d01ce))
