Can't enter itherian boss portal in Vulcanar sigil realm

Version: 0.4.3

The portal isn’t its normal color as well.

I think a teleportation rock is underneath it.

I can’t complete the sigil as a result.

Screenshot below

The rock disapperaed (visually) after battling a batch of eggs! :frowning:
The rock still functions underneath (teleports to another part of the map)

When coming back out of the portal, it still looks like the image below.

What a mean portal.
