Well seems this server problem is widespread on all maps with glitches, crashes and progress loss.
I've been playing on a private server for quite a few months (we have 4 maps going at the same time and chip in for the cost with 10 licences on each so a max of 10 at one time, we never reach that), that means we can transfer our characters within our cluster to another map and we have NO game issues.
I recently decided to try one of the official EU servers and created a new character on the Ragnorok map. Looking for a place to build a temp shelter at the start was stupid as players had put metal or stone pillars everywhere (even underwater) to stop people building. I was fortunately helped by someone who gifted me a Wyvern to fly around and I eventually found somewhere (took ages) where they didn't realise was a good spot and hadn't littered it with pillars.
I was later ready to tame a Barry, Anki and Dodic to get resources to build easier. What a joke that was, couldn't pick any of them up to carry back to my taming pen no matter how hard I tried. Went back to my private Ragnorok server to test picking up a Barry with a Wyvern on there and had NO PROBLEM.
I've now just realised what the problem possibly is, AND THAT'S YOU LOT. I bet this pillar problem is on all the official maps and its destroying your gameplay. The server has to try rendering in EVERY time you move all those new pillars and render out the old ones and the servers are prob maxed out most of the time. I'm sorry but you need to look at what you are doing yourselves and not blame the game, developers or the servers. I think the developers need to make sure there is a maximum amount of build items you can make and place to stop this and that for a group not just on single player. Look at whats been done by other players on the servers you are using and I would bet my shirt its on them all.
Just going to add this is a PvE server NOT a PvP one. Also seems those players and groups with  as names and when they chat we have  as well in the game chat window are the main culprits on the map I'm on putting up those pillars, go figure. Might THEY be the problem? You decide.
