positions not showing to place garrison

so, sometimes when im running an adventure, some spots to place the garrisons dont show, some other times, they show, whats wrong?

for example, this block on island of pirates

before (X3 garrison place in front of that bush):
iotp map

now:
iotp bug


it has nothing to do with the update for new path, since i made that guide after the repathing, sometimes the spots show, sometimes they dont, it happened already in several adventures like witch of the swamp,black knights, outlaws...and its a really big problem, its affecting my guides

yep... we almost have to make 2 guides to cover the spots that decide to apear...

this has ahappened to me on SFTR, sometimes i can skip a trap and other times i have to attack it cause my normal spot wont show up

I find that if I place generals "near" where a path or tree is blocking the place I want, and then go do something else and later logout and log back in, the obstacle has sometimes disappeared. But I don't know what triggers it; going to the test server seems to help.
