Work from the live symptom to the relevant requirement, setting or support report.
A vehicle is missing from dispatch
Official help points first to Maximum distance from vehicle. A narrow search setting can exclude an otherwise useful resource. Open the vehicle directly and confirm its location and current status. TKB diagnostic advice: also check the active list filter, any ARR station restriction and whether your desired unit has already been committed elsewhere.
If the vehicle is visible but does not deploy, inspect available personnel. Official help identifies insufficient crew and personnel away on training as possible causes. For specialists, verify that the required trained personnel are at the correct station and available. Buying another copy of the same vehicle will not fix a staffing shortage.
A mission is eligible but rarely appears
The potential-mission list distinguishes eligibility from actual generation. Official help advises checking active buildings and extensions, the relevant coverage area and a suitable nearby POI. Even when the conditions are met, selection remains random. A green entry does not promise the mission will arrive during your next session.
TKB recommendation: inspect the mission’s generating service and local geography before moving buildings. A matching POI on the other side of the country does not solve a local range problem. Use the game’s range controls deliberately, and compare several sessions instead of treating a short dry spell as proof of a defect.
An incident will not finish
Open the live incident and read the remaining requirement. Separate a missing response resource from a transport request, a vehicle still travelling and a mission that has changed. TKB diagnostic advice: use the actual shortage message as your next action, not the icon colour alone. Reopen the view if you suspect a display delay.
Check the exact variant and any new work created during the incident. Do not assume an ARR with the same broad title covers every possible development. If an alliance member owns the outstanding transport, contact the appropriate person or authorised alliance role rather than sending unrelated appliances.
Routes or performance seem wrong
Official route documentation says routing uses periodically updated OpenStreetMap data, rather than a real-time view of every road change. Record a reproducible start, destination and route issue. A map correction may not appear immediately in the game.
For lag, TKB recommends comparing the same action with optional extensions disabled and fewer unnecessary panels visible. Record whether the delay occurs on the native game, a particular browser or one device. Preserve your login details before clearing browser data. Do not delete buildings or reset major configurations as a first troubleshooting step.
Send a useful report
- Include your UK account name, device, browser or app version and approximate time with timezone.
- Describe the exact steps and what you expected to happen.
- Provide the affected mission, building or vehicle link where possible.
- Include the complete visible error and a screenshot with private information removed.
- State whether the issue reproduces without optional tools.
- Use official support for account or game faults; use the relevant creator’s support route for an extension-only fault.
