NPC Spawn Issue: OOT Dwarves

[Rhambuk]

There are 3 dwarves that spawn in the backside of sister isle in oot,

Glendl Vargnus
Elona Tunbrin
Hugan Tunbrin

The first 2 respawn in 6and Hugan spawns in about 18

I used the wayback machine but couldn't find anything within the current time frame. I will keep looking for solid evidence but it doesn't seem right that 1 would spawn 3x later than the other 2.
