[Minor bug] Clear slimes spawning during the invasions

[PeachBurger]

Issue Description

I'm not entirely sure that that is intentional or not, but clear slimes are able to spawn during the goblin invasion.
Expected behavior: Biome creatures are not supposed to enterfere the invasion mobs, at least according to the base game behavior
Actual behavior:

Mod list: Starlight River v0.2.9.2
Reproduction: Every time during the invasion, even in hardmode

I didn't try to recreate it with other invasions, but I have sneaky suspicion...

Additional context and log files:

Starlight River v0.2.9.2
tModLoader v2026.3.3.0
Terraria v1.4.4.9
