Demo 0.9.39 | Capture your grid. Help us track down bugs.

Mini Grid · published

This update brings two practical additions to MiniGrid: Photo Mode and Bug Reporting. Your growing grid deserves a good picture—and when something goes wrong, being able to preserve the situation can make a big difference.

Thank you for playing and for every detailed suggestion. We have also been working on large-grid performance to reduce the stutters that can interrupt building and inspecting a late-game network.

Photo Mode: take a picture of your grid

Open Photo Mode from the pause menu

Choose Photo Mode from the pause menu to hide the regular interface and keep the map and network in view. The simulation stays paused while you pan and zoom to find your composition.Press S to take a picture, with a shutter sound and capture animation. A thumbnail and save location appear afterward, so you can find your shot. Press L to toggle meter labels, or O to open the screenshot folder.

When connected to Steam, you can also choose to add the image to your Steam screenshot library. You decide whether to upload it publicly in Steam. We would love to see your layouts, growing networks, and close calls.

Bug Reporting: preserve the situation, not just the description

You can now choose Report a Bug from the pause menu. Describe what happened, what you were doing, and how to reproduce it. Details such as the month, the affected equipment, and whether you closed a circuit or removed a line can help us investigate.

Submitting first prepares a local report package and, during an active campaign, a separate report save. Your existing save is not overwritten. You can choose whether to attach the save and system information; contact details are optional. A save helps us reconstruct the problem, while system information can help with performance and compatibility issues.If online sending fails, the report package remains on your computer. You can open its folder and use the email option, manually attaching the save as prompted. We hope this makes it easier to report the problems that are difficult to explain from memory alone.

More work on large-grid performance

This update reduces repeated work in power-flow calculations, moves some network validation work to the background, and improves meter labels, hover detection, and rendering updates. The focus is reducing CPU load and stutters as the network grows and demand changes.

These changes do not alter the power-flow model or supply assessment rules. Performance work will continue. If you still experience significant stutters, please tell us the grid size, month, and action involved, and attach a save or system information if you wish.
