This Logic change will cause sea creatures not getting detected by the alert feature at all. Even then, when the mob spawns behind blocks and gets pulled into the player's line of sight a second later.

I think there is a "SkyBlock Mob first time see event" or something especially for this
This Event does not exist, we need a new event for this since this very behavior is needed in multiple features. see 3cd3958

This Logic change will cause sea creatures entirely not getting enounced by the alert feature, even when they Spawn behind blocks and get pulled into the player's line of sight a second later.

that event doesnt mean first time you ACTUALLY see the mob, its just the first time that mob is detected

I'm talking about this

The mob spawn even already handles "first detection". otherwise, the names would be horrible wrong or the spawn event would fire multiple times for the same entity, right?
