No warp in AND out (pk/stealing or win/die quests)
Good.
For the part of the stealing and PK sectors:
Add a command or such that toggles a plot/sector stealing. It should also warn a player upon entering that they have entered a stealing zone or whatever.
I see no point in this, stealing should be all or none.
Anyway here is actual stuff that is broken / I think should at least be adjusted in V3. I'm sure everyone here has a million ideas of how to make the game more fun and QOL improvements for admins. If you wanted all of those ideas it will take me a long time (lol).
There's probably more then this list, can't remember everything

.
Multiuse fail XP is broken. Multiuse in general feels like an afterthought.
Bumping.
Trade spam infinite menus.
Trading to go above max burden.
Hardcored crap it takes forever to resolve trees having Forest on them, black magic, being able to auto mine / perform other future auto actions with other tools, etc.
Item reset / item relational code / world change detection - slow sometimes i'm assuming it goes by in game ticks. It would be better if it went by real life seconds but that could be far too difficult. Example open a trap door by trigger and it ALWAYS closes 1 second later.
Drowning monsters.
Make it so monsters never drop below 15 Mana when they cast to remove free icing / blinding / mana denial.
Making the allow only one item code actually work in all cases would significantly improve the way the game could be played.
Allow playing of mp3 files so that music files don't add up to a massive file size.
Make stealth xp based on the monster level in some way. Scan levels can be adjusted. Makes finding optimal training spots more challenging instead of always finding the first 2x scan monster and camping them.
Untamed mules/traders staying around and not being able to be killed.
Treasure ini is bugged in the the fact that if a monster has a 100% drop rate and the treasure ini has a 100% drop rate sometimes the item won't drop. Seems like it happens if the monster dies in an area where lots of items are on the ground.
Siege - make it so that certain monsters can be flagged so they won't spawn in the siege since they are not appropriate for it.
Sometimes an item will get bugged in the world in a spot and it causes everything around that spot to sort of glitch out. I believe you can reproduce this by casting a -1 improve on an item or something of that nature. I think the best way i've found to clear such a glitch to is restart the world after attempting to clear the bugged spot.
