Loosing Hydrogen

Hello Nikos,

thank you for reaching our forum with this problem.

Can you please provide me more information on the subject?

I have tried on my side, but it seems that all hydrogen and hydrogen-related blocks are working as expected.

Does this issue happen in single player or multiplayer to you?

Can you please share me some reliable steps to reproduce?

If you are experiencing this on online multiplayer, please share me the affected blueprint.

You can access your blueprints files by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers\Blueprints. Select the correct folder where your blueprint is saved (local or cloud), zip the file and attach it here.

If you are able to reproduce/observe this problem also in single player world, can you please share me the affected save file?

You can access your save files by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers\Saves. There should be a folder with your SteamID and your saves.

Please zip the file and attach it here. If you are having difficulty attaching files you can optionally use Google Drive. When sharing a google drive link please make sure it is set to be downloadable by anyone with the link.

Also please try to share a video depicting the issue on your side if you are able to grab it.

Thank you in advance.

Kind regards,

Hello Nikos,

Thank you for the update and for sharing the blueprint. I appreciate your effort!

Since the issue seems to occur randomly on a multiplayer server and you haven’t observed it in single-player, it’s a bit tricky to pinpoint the root cause without more details. The blueprint you provided is quite large, so in order to investigate effectively, I’d still need some additional guidance or reproducible steps.

Could you please try to capture a video of you actions prior this issue starts to occur if possible? This would help me understand the context and specifics of the problem.

Additionally, while you mentioned the mods on the server are minimal, please note that we don’t officially support modded worlds, even with minimal mods. For accurate testing and troubleshooting, I kindly ask if you could try reproducing the issue in a vanilla (no mods) world or server.

If you’ve noticed any patterns - such as specific actions, events, or scenarios that tend to trigger the issue - please share those as well. For instance:

• Does the hydrogen loss occur after respawning, pasting grids, or interacting with specific blocks?
• Are there specific actions happening on the server when the issue occurs?

Without more concrete steps to reproduce, it’s difficult to fully isolate the cause. If you’re able to grab a smaller, simplified version of the blueprint where the issue still occurs, that would also be very helpful.

Looking forward to your reply, and thank you for your continued patience and cooperation.

Kind regards,
