As reported by DeeBoFour20 at http://en.wikipedia.org/w/index.php?title=Wikipedia%3AHelp_desk&diff=564750403&oldid=564748007 you cannot link to the en-Wikipedia article [[DmC: Devil May Cry]] within a timeline; apparently the "DmC:" is interpreted as some sort of prefix and breaks the link. Linking to that article with exactly the same code outside the timeline environment works, so it's likely an extension issue. [[:DmC: Devil May Cry]] links to the article. See http://en.wikipedia.org/w/index.php?title=Devil_May_Cry&oldid=563543799 for a live example. I haven't tested any other pseudo-prefixes beyond [[Devil May Cry 3: Dante's Awakening]] which is rendered correctly.
Looking at the source and some experiments, it appears EasyTimeline assumes 2 or 3 characters followed by a colon is always an interwiki link. It doesn't actually have to do anything for interwiki links. MediaWiki handles it so for example: http://en.wikipedia.org/wiki/de:Berlin redirects to http://de.wikipedia.org/wiki/Berlin while http://en.wikipedia.org/wiki/DmC:_Devil_May_Cry is an English article since dmc is not an interwiki prefix. Huon's fix [[:DmC: Devil May Cry]] only worked because it has 4 instead of 3 characters before a colon, and not because it starts with a colon. http://en.wikipedia.org/wiki/OT:_Our_Town is an English article but [[OT: Our Town]] and [[:OT: Our Town]] would both fail in EasyTimeline. [[OT%3A Our Town]] would work, but would need a piped link to avoid an ugly display.
