Push's post in Engine operation with a large online was marked as the answer
There have been a few official game releases with the engine. Leafling, Nightmare, and Pirate Souls. with 200-300 concurrent players being the peak of what has been tested.
There are still some major issues on Main branch 7.1 and it would not be advised to release a game on it until its complete, and the stable version 7.0 may not have some features you want like instances.
Push's post in Item Price and Shop Selling was marked as the answer
You can set the sell price of each item (in the Shop) - which makes it different then it's default sell price (value set on item itself)
If you do not set a sell price, and have 'Blacklist' enabled - items sell at their default sell value.

There is a community made GUI editor:
This is also a good tutorial on editing the GUI manually though the JSON files:
I believe the format for the numbers is (Position x, Position Y, Size X, Size Y)
But take that with a grain of salt, I haven't touched the editor in some time.
Push's post in Spawn MOB/NPC only once was marked as the answer
Only way to do that without source modification is using an event.
You can use a map event or common event:
1. Create a Global Variable: Set Global Variable to 0, make it 'Integer' and name it something you will remember. For this example I named it 'NPC1'
with Map Event (Trigger = Autorun)
2. Conditional Branch - if NPC1 variable = 0,
3. Spawn NPC (NPC1)
4. Set variable NPC1 = 1
Push's post in How make usable paperdolls was marked as the answer
You can make armour/weapon paperdolls by taking the base character sprite (i.e. Human.png) and drawing in the items on a second layer.
Then take the character layer out and the remaining will be just the item layer, save that .png in paperdolls and that's all.
Push's post in NPC (on death for party) not working on 6.2 Build 421) was marked as the answer
I realized a server config was added for this in the 'config.json' file and is defaulted to '0'.
"NpcDeathCommonEventStartRange": 0 (change this number to allow 'NPC death for party' to be active.)
Push's post in Change the GUI size (Answered) was marked as the answer
1. Edit the window itself by changing the "character.png" file under Client and Editor/resources/gui
2. Change the window's position after that by editing the "CharacterWindow.json" file under Client and Editor/resources/gui/layouts
3. Edit the very first line called "Bounds".
4. Make sure server and client are closed.
Thread Closed. The Question has been answered.
