There is a known outstanding bug with LOTS of mods that cause blocks to disappear from your ships and or not able to be placed down when ANY mod is updated.

This is something that is out of my control that Keen has to fix and the current only known workaround is to clear your mods folder or clear just this mod from the mods folder and allow it to re-download the mod again.
Please refer to this topic I have linked below:

Anyone that has blocks disappearing please clear your mods folder and let it redownload the mod. This is something out of my control that Keen has to fix.


For a mod that is not appearing in your G menu, you must delete the associated SBM file from your Space Engineers mod folder (on both client and server if applicable) and let it redownload. The name of the file will match the workshop ID of the mod, found in the URL of this page directly after "filedetails/?id="
