Rome2Rio alternative for the Balkans/Eastern Europe?

So I've quickly come to find out that Rome2Rio is terrible when it comes to Eastern Europe and the Balkans.

Here's some examples:

• When trying to go from Levoča (Slovakia) to Lviv (Ukraine), R2R suggested an insane series of 5 trains, or a series of 4 buses (that included a bus that only runs monthly.) There was, in fact, a single direct train as well as a direct bus. - See Question.
• When trying to go from Dubrovnik (Croatia) to Trebinje (Bosnia), R2R is telling me the only way is a 7-hour, 2-bus odyssey via Montenegro. I know for a fact there's a 45-minute daily direct bus.

Furthermore, when looking at suggested bus routes that it gave me in Slovenia, I found that R2R was linking to schedules that were 4 years old.

So I've given up with Rome2Rio in this part of the world. Are there any route planning websites that are reasonably up-to-date for this region? Or is it still a matter of "use google" and "Site X is great for Croatia, Site Y works for Czech/Slovakia" etc?

There is a question about Rome2Rio alternatives here: Are there other sites such as Rome2Rio?. That question offers three alternatives:

• GoEuro.com - No route found between Dubrovnik and Trebinje
• Waymate.de - Unable to find Trebinje as a destination
• RouteRank.com - No route found between Dubrovnik and Trebinje

So Rome2Rio is already a superior choice to these three since it did suggest a [terrible] route to get between these places.
