To restart your campaign in ARMA Reforger Overthrow you must do the following:
Overthrow folder in My Documents\My Games\Arma Reforger\profile\.db. This is the default location of the "profile" folder. This location may vary if you specify a specific profile folder.If you are using a game-server hosting provider you should contact their support if you cannot locate your "profile" folder. If you are using a hosting provider and deleting the save files does not reset the campaign, it is becuse they are caching them and you need to recreate the entire server again or contact them and tell them to not cache your files.
Overthrow saves your progress automatically every 10 minutes and when exiting the scenario or shutting down your server. In addition to this, officers can manually save the game.
Overthrow Reforger does not currently work in SP (Single Player) on Xbox. There is currently no way to provide a persistent save on Xbox in the base ArmA Reforger game. Bohemia Interactive will be releasing a fix for this in the future but we don't have an ETA yet.
In the meantime, you can still join any of the cross-play-enabled public Overthrow servers by searching for "Overthrow" in the server browser. You can also host your own server via Steam on a PC or by renting a server from a provider (we recommend 0grind.io servers by Bacon).
Overthrow uses a system called "Enfusion Persistence Framework" to save/load. This feature will eventually be included in the base game but there is no ETA for this. Until then there will be some inconsistencies with the items that will actually be persistent. We recommend placing your most important items in an equipment box before logging out as this will usually work a lot better than keeping it in your inventory.

First, you should determine if the issue happens with a base game scenario and not just with hosting Overthrow (including while not using extra mods). If you have issues related to client connections, etc. you should checkout the official ArmA Discord or forums for help instead of the Overthrow Discord.
If the issue is specific to the Overthrow scenario, then the Overthrow Discord would be the appropriate place under the #reforger-support channel.
Weed will be restocked daily at 7am, for weapons and ammo you will need to restart the game or your server
See Dedicated Server Setup and Overthrow Config
Only on a dedicated server currently. See Overthrow Config
In single player you should automatically be an officer. On dedicated server you need to login as admin by typing #login <password> into the chat box. Once an officer you can assign others as officers in the Resistance screen. You can permanently make yourself and others officer without logging in as admin using the Overthrow Config
Most mods that add weapons/vehicles/clothes/items will work with Overthrow. Those items will be available in shops/gun dealers as long as they are configured correctly and added to the Entity Catalog for a faction that is configured for Overthrow (ie US/USSR or RHS factions if you are using the RHS Compatibility mod). Note that gun dealers will not sell weapons from the Occupying Faction, and you cannot procure vehicles from the Occupying Faction at bases. Non-lethal items from the occupying faction will be available in stores. Unarmed vehicles may require further configuration to show up in civilian vehicle stores.
For a list of mods that have been confirmed as compatible with Overthrow, check the #reforger-compatible section of the Discord.
