Softlock at stage 20 of Family Crest; player cannot obtain the third crest piece if lost or not picked up
What I did: Defeated Chronozon, but did not obtain the crest piece he drops
What I expected to happen: To be able to obtain it by fighting Chronozon again.
What actually happened: Chronozon does not spawn at quest stage 20, and no other way to obtain the crest part exists.
IDs of related NPCs/items: Chronozon (NPC 667), Crest part (Item 781)
2009-era source (if relevant): Unlike the other two crest parts, no dialogue transcript exists for retrieving the crest part from Johnathon like the other two if lost. So, Chronozon is clearly meant to be the source for retrieving it again. All sources suggest implicitly that Chronozon is fightable as long as the quest in in progress.
Sources such as https://runescape.wiki/w/Chronozon?oldid=949577 further suggest that specifically, Chronozon should only drop the crest part while the quest is in any later stages.
The most accurate solution would probably be to make Chronozon spawnable at any quest stage other than 0 and 100, and only drop his crest part at ones within that range from 19 onwards.
