Windows .exe FTB Unleashed Server / Client issues.

[SirCapnObvious]

I'm currently hosting an FTB Unleashed server through MineOS+ (http://mineosplus.org) and I'm just running into multiple issues that are... a pain in the rear to say the least! This is hosted on my internal network (running it on my sever at home) and this is Server 1.1.7 and Client 1.1.7

My most recent experience:
I log into the server, start running around... I see that my frames are LOW... 16 FPS, which is bizarre, I'm always in high 80's 90's.. etc. So my first instinct, ah yes... let's restart the FTB Client.

Apparently, big mistake. After I restarted the client, every time I try to log into the server, I get to see a glimpse of the chat.. and it looks like the screen begins to render, and boom Minecraft crashes and gives me a long error. After "browsing" over the error, I seen Render errors... so I removed my Texture Pack, seemed.. like it might help? No luck. I haven't heard any complaints from the 2 other players.. But they're not on nearly as much as I am.


Well, anyways.. it first began when I set up a Quarry in Twilight Forrest, I had used an Ender Chest, which caused the chunks to reset and lost my quarry every time the server reset.. took me a little bit to figure it out, well this started happening at about the same time, and my first crash I believe I was logged off in TF so I figured that was the issue. I was able to log back and and begin playing again by deleting my characters Player.DAT file, and using one from a previous backup. (Assuming it has to do with my characters location?)

Well I thought everything was good so I continued playing like normal, and this morning got hit with it again.. I've tried everything minus reinstalling the client on my computer. I've been enjoying this modpack but running into errors like this has been detrimental! Just looking for any insight, maybe some ideas to try? I've attached the crash logs.

Thanks in advance and look forward to some ideas!

Well, I am playing again, by using an old Player.DAT file, just curious if anyone can tell me what is causing it, so I can stop doing whatever it is?! Roar... I'm tired of having to use NEI to re-gear myself, lol.. really hate for it to happen to other players.


EDIT:

I found out what is causing my Player.DAT file to be deleted... it's the Iron Tank http://feed-the-beast.wikia.com/wiki/Iron_Tank

Few odd things I've noticed:

• I only start crashing if I reload the FTB client in the same chunk as the Iron Tank.
• If I move the Iron Tank to a different chunk, and reload the FTB client in that chunk... I don't crash.
• If I keep the Iron Tank in it's current location and log off next to it.. I'm okay, I can log in and out hundreds of times with no issues, but once I close the client and try to log back in, it crashes.. and can never join the server again. (until my Player.DAT is deleted)

Still curious on if there's anyway to ensure this doesn't happen again? I'm okay with avoiding Iron Tanks, but I could have sworn I had this issue recently, I finally gave up and restored the server to the previous day.. I wasn't using Iron Tanks then.


So current status:

I'm able to play after removing the Iron Tanks manually, first deleting my Player.DAT so my character spawns at the spawn point, then running back to my base and destroying the Iron Tank. Hope this at least helps somebody else get back to their server!
