Bug reports

Send a bug report or a feature request from the game, and the commands that help find a problem.

Report from the game #

Run /buildprint report in chat, or click Write a report... next to Report a problem in the Help tab of the settings.
Choose Bug or Feature request, give it a title and say what happened: what you did, what went wrong and what you expected.
Under Attached you see everything that goes with it: your system, your mods, BuildPrint's state, the game log and a screenshot. Click one to leave it out, or to see exactly what is sent. Names, folder paths, addresses and chat are taken out first.
Click Send. Nothing leaves your computer before that.

A contact is optional. Add your Discord name, or sign in, if you want an answer.
When a report you sent gets an answer, the game tells you, with a button to read it. The reports you sent are under Sent on the same screen.
After a crash or an error in BuildPrint, chat offers once to send a report. Offer to report errors in the Help tab turns that off.

You can also ask on Discord. A picture or a short clip helps.

Command	What it does
`/buildprintdebug report`	Writes the versions, your settings and every loaded build to `logs/latest.log`, to send along with a report.
`/buildprintdebug dirlog on`	Logs every barrel, piston, observer or crafter placed: the way it should face and what the server made of it. For blocks that land turned wrong.
`/buildprintdebug printlog on`	Logs every block the printer tries and what held it back. For the printer stopping.
`/buildprintdebug profiler on`	Shows timings on screen and logs slow frames. For lag.
`/buildprintdebug hardcoded off`	Turns off BuildPrint's special cases for single blocks, to tell whether a problem is about one block. On by default.

The logging commands are off by default. Turn them off again with off. /buildprintdebug on its own lists them, and whether each is on.

Waterlogged blocks are not placed unless the experimental water bucket setting is on.
Invisible item icons after switching shaders are a bug in Iris on Minecraft 26.2. Scroll through the creative item list once to bring them back.
