For some reason I have been very unlucky on the server I play on.
I have died and lost around 2-4 pairs of long fall boots, in addition to a lot of iron tools and armour.
I die... Quite often. I don't know why - build a powersuit helmet chest and legs with full on advanced playing at max, and long fall boots, stepped into a hollow hill...
My game froze.
When it restarted, there was an explosion, a spider noise and then "natnif36 has been pummelled by a slime beetle."
All in the space of 5 seconds.
I spawned at the TF spawn, roughly 1200 metres from my portal home, and starved once trying a straight run back,so the next time was an extended cross-country journey involving killing many passive mobs for their flesh.
A while later, I arrived roughly where I had does, and began looking for my stuff.
"natnif36 was pummelled by a slime beetle".
Fuuuu...
I then had to leave. Not rage quit etc, but genuinely had to leave the Laptop.
One time that particularly annoyed me was when I was assaulted inside my home, do to a design feature planned which I currently cannot afford/be bothered to dig out my underground cavern. Anyways, I died inside my chunkloaded house, and then a few minutes later, as I was going to get my stuff... The server crashed.
I did not know this, however when I arrived at the scene, armed with a stone sword, however neither my drops, nor the several skeletons, pair of angry Zombies nor HUGE blue slime that had killed me were there. For some reason chat was fine - no chat lag and running smoothly. I then tried opening a chest and got an "End of stream" error. Ie the server was dead. I wasn't carrying anything particularly valuable, however I was carrying a bunch of ars spells, and also all my runes (about a stack of each). Also an omniwrench.
Then there was the time I tried using (portal gun) portals on the ground to get back after a long nether mining trip - long fall boots, steel TiC tools and ars flight, in addition to a portal gun that someone had gotten in a loot bag (Poppycocks). I spent a few hours mining, and had my right click portal
Set to my base camp/nether portal, and decided to go home, so I placed my left-click portal and hopped in. Lag, lag, lag, *slurpsoundthatportalsmake*,*slurpurpurpurpurp*, "natnif36 suffocated in a wall".
After that I haven't made armour since, and walk around with a rift blade donated by Kuu, and a bone frying pan...
Amidst my stack of potash apples, of course.
I don't want to spend resources on something that gives me nothing valuable in return, and a suit of armour which would give adequate protection to raid enough hollow hills to pay for itself, wasn't affordable. And I don't like making anything that will be soon obselete. For example non-pick axe wooden tools.
