I missed this earlier.

moved from comments I guess this is where it goes:

I was wondering where this came from It took me this long to track this down because nothing in the normal logs indicated where it came from and i have about 150+ mods going, but there was a message that started streaming on my screen after the update: "GridKernelImplementer.GridKernel[Implementer.UpdateModules]: Caught an exception in InventorySystemModule" I literally had to cut my ship in half power the dead half then repeat again until i figured out it was the 1 multitool i had in the nose of the ship. Could you maybe add the mod name to the messages, because nothing is going on in the spaceengineers.log to indicate a source of the problem.

log files are all 0kb and spaceengineers.log is just line after line of:

Some other mods have null cargo boxes that are intended as access points for cargo. This mod throws an exception when encountering these modded cargo containers.

playing around with turning off and on mods and it seems there is a problem with it trying to put things in several different modded block inventories.

"GridKernelImplementer.GridKernel[Implementer.UpdateModules]: Caught an exception in InventorySystemModule"

There are no actual error though, these blocks function as intended.

I am sure there is a reason for the exception but it will cause conflicts in some mods. I changed these lines to get the exception to stop.

// if (TargetInventory == null) throw new ArgumentNullException(nameof(TargetInventory));
// if (SourceInventories == null) throw new ArgumentNullException(nameof(SourceInventories));
if (TargetInventory == null) return 0;
if (SourceInventories == null) return 0;
if (SourceInventories.Count == 0) return 0;


It finally stopped when I set the only valid type to be IMyCargoContainer. so it seems i have at least one of each of the other types that break it all.
