Hi!

So, I had killed a some Manshas in Mansha forest with my season alt. Found 2 scrolls that are supposed to summon Giath (no longer have the name of them as they're both used). Put the scrolls in storage then withdrawn them with my main (non-seasonal character).
Today, I right-clicked a scroll which took me to the Goblin Cave. While there I used this scroll and began summoning. Beyond my character holding the scroll there was no animation from any boss appearing while channeling.
When channeling was done, nothing happened for a while so I ran away and went to Velia rq, turning back around half way and went back, thought I'd try my second scroll as well.
Had to remove the quest.

Did the same again, same thing happened. Derped around a bit in the cave, went here to write this and just as I was writing the previous sentence Giath suddenly appeared out of nowhere. I've no idea what's going on, it's been minutes since I used the scroll and there was no animation anywhere indicating anything was happening after I had used it. The server often suffer from massive lag during certain boss encounters (looking at you Garmoth) but there was no boss up nor recently killed at the time.

Not running Giath nowadays (and haven't done so for over a year) so perhaps this is normal for this boss, I don't know. To me it felt weird.
