Alpha 15 Workers stop working and cannot do new tasks

Support Resolved Reports
1

Summary: Engine error box pops up and some workers cannot continue with their tasks or be assigned new tasks.

Steps to reproduce: It appears to be when building, as the farmers are fine.

Expected Results: Workers finish their tasks, and then are able to queue new tasks.

Actual Results: Workers just stay on one spot.

Please see bug reports below (there were a lot of errors but it appears that the same error pair (error 2 and 3) occurs for each worker), I hope all are useful:-

Error 1 (could items in their backpacks be causing this error?):

Error 2 (this appears to be the issue when the workers don’t work anymore):
