DotA 6.87c5 LoD

Guys i have bug with joining lan parties with my friends...on this and other 6.87c versions.

We played 2-3 days before 5-6 matches of this map but now we cant.

For example when i create map mine friends join but downloading map end at 36 number...and i cant press Start game.

So we need to go back to old maps like 6.86d1 and older maps...

I had problem also with 6.87b versions before....

Does anyone have same issue or those anyone play lan matches like we do

P.S: I already copy game.dll for map file size file...
