ZZ Rot portal can be triggered as a global bug.

I will paste the same thing i told a rioter over twitter:

here's the thing , i dont know how the wolves are coded but i set up a zz rot portal (first time i buy it ever) on wolves pit , as shen with sunfire up the small wolf started moving inside the pit and some times they would go out like a pull from mid lane gave it no importance until we saw we were watching enemy base and next time i saw we were able to see every midlane area and minions were walking like drunk it was hilarious but then they'd started stucking between nexus towers and not spawning ( or not visibly doing it) http://www.replay.gg/search/euw/paxco# … its the shen game in the replay you can see weird items spawn invisible but highlited in the areas where creeps were stucked Paxco 50hp invisible poles

you should be able to understand it if you watch the game, in the replay it doesnt seem as buggy as live but still is obvious
