It's a common situation for Chinese games. MiHoYo's games also use ripped models and textures from other games during development. Sometimes, these even make it into the release.
Astra Yao's Signature Weapon Effect (Hair): This effect is always active, regardless of skill use.
Evelyn: Currently, Evelyn does not have any effects in this beta version.
I would like to apologize for a mistake i made in last beta. I incorrectly stated that Miyabi's glowy hair was her signature weapon effect. In fact, she had no effect in the first beta version. I regret any confusion this may have caused.
Any bug in character menu is not my fault. If anything is missing, I tried my best (without falling asleep at the gameplay) translating the kit with DeepL.
