ok guys i have a very confusing problem

the map i like to play is LoD Dota 6.86b2 as far as i understand this map is only compatible with version 1.26a
and keeps crashing with version 1.28.5

When I connect to the server using 1.28.5 I can see the game [STATS] LOD rm2 and can enter it but crash when the game about to load

when i connect to the server using 1.26a I CANT see any [STATS] lod games

can anyone please explain what is going on.
