Wacky Sim crossing problems

Well this is freaky, been having problems TP over last 3 days and today I narrowed it down as seems to be only to and from Andraca my home sim, so to get back I TP to Loeopa next sim over and couldn't fly in from there due to ban lines I though, so went around to Pruni to the North and walked up the road bang into an invisible wall at the border. There seem to be trees jammed in the road too for some strange reason. A neighbour in Pruni has had no problems, so I logged on simultaneously with my alt and walked up the road and found the world ended at the border, nothing but ocean and an invisible wall. But I could see my alt with my original character but not the other way round, so I fly my alt the other direction and by going the long way around I can get to the other side & my main character but still can't cross between the other 3 sims. So I can only enter my sim from one direction, and assume this even applies to TP for some reason.

For some reason too none of the trees at the border are clickable either.

I sent a sim down report, "Hi, are you online?" to half a dozen Lindens I've never met yet. But being 18 Hours ahead few Lindens are about if any when us Australians/Asians are on the grid.

I can even hear chat from each char across the border ok.

Oddly enough the good side is the one that the road surface dissappeared from a few weeks ago and hasn't returned

Hmm, more on this it appears my sim as walls on 3 sides preventing any crossing, even TP, even TP from sims on opposite sides from mine are affected, so imy sim must be stuffing other peoples tp's up which if there are other sims with the same problem then a lot of our TP problems could be due to sim problems inbetween our position & destination, it also explains why if I can't get somewhere after attempting TP 10 times if I TP3 or 4 sims away, I have no problem, then if I go back to that sim the problem occurs.
So perhaps other people should try the walk out / walk in test if they are having dramas.

I think my sims been restarted or the problem has dissappeared because walking & TP are ok now, but then again smaething happened around this time last night TP seemed to come good too. So see what happens tommorrow I guess.
