Won't Fix

i host unmodded red ship v2 on lowest settings->they join and get stuck on menu->they alt f4 and get asteroid body->they f5 and it works, and its the same for me joining them even after adding mods to that world. if we add mods on the blank world its the same, but if we do unmodded solar system or anything else modded it gets stuck loading at 100% we both have good internet and running it at lowest settings possible.

Hello Jerey,

Thank you for reaching out on the forum, and sorry to hear you're experiencing this issue.

From the details you shared and your logs, it looks like you're joining a lobby (peer-to-peer session), in peer-to-peer sessions, the host’s machine handles world streaming and synchronization, which can sometimes cause the game to get stuck at 100% loading or result in spawning as an "asteroid body" if the handshake fails.

We recommend trying the following steps to troubleshoot and potentially resolve the problem:

Verify game files on Steam:
- Right-click on Space Engineers in your Steam Library → Properties → Installed Files → Verify Integrity of Game Files.
Clear cached configurations:
- Delete the SpaceEngineers.cfg file (found in AppData\Roaming\SpaceEngineers folder). It means your game configuration/settings will be deleted. This can be re-configured in the game settings.
- Clear contents of the ShaderCache folder in the same directory.
Test joining a purely vanilla world:
- Host an Empty World with no MODs active.
- Have the other player try joining this clean test session to check if the base connection and sync work properly.

If the issue still occurs after these steps, please send us updated logs from an attempt to join a completely vanilla world (no MODs active).

Kind Regards,

Hello Jerey,

Thank you for sending the follow-up logs. We've reviewed them and compared them with your initial session logs.

The issue appears to occur in unmodded worlds. When MODs are present, the loading process typically takes slightly longer, which may give the game enough time to complete the sync process properly.

In fast-loading vanilla worlds, the game might begin simulating before the client has fully synced, which can lead to the 100% loading hang or the "asteroid body" issue after joining.

To help us investigate this further, could you please clarify the following:

How is your friend joining your sessions, via Steam overlay > Join Game, in-game invite, or direct connect?
Does the issue occur regardless of who is hosting (you or your friend)?
Are either of you using a VPN, firewall, or antivirus software that could interfere with peer-to-peer connections? If so, please disable them and check if the issue still occurs.
Does the issue still occur when hosting a Dedicated Server through the Space Engineers Dedicated Server manager tool from your Steam Library?
Could you also provide a log file from your friend during a session where the issue occurred?

Thank you again for your continued patience and cooperation.

Kind Regards,

Keen Software House: QA Department
