Issue description
There is an issue with surface placement involving the amphibious trucks. When un-assigned amphibious trucks are available AND the 'don't use for construction' filter on amphibious trucks is selected, the amphib trucks appear to take surface tile placement jobs but don't actually respond, and effectively lock the job response out for other vehicles, causing surface placement/removal to not function. When this is occurring, by removing the 'don't take surface construction' filter temporarily the trucks will complete the surface placement job. This appears to be niche issue depending on overall vehicle availability and whether amphib trucks with 'don't take surface construction' filters are set. The amphib truck construction behavior seems appropriate based on the filter settings for other construction and it only appears to be an issue (some of the time) when idle, unassigned amphib trucks are available and surface tiles are placed for construction.
Reproduction steps
No solid reproduction steps determined other than amphib trucks being idle and unassigned when surface tiles are placed for construction/destruction and the 'don't take surface construction' filter is set for amphibs. It is an intermittent issue and may be related to overall truck availability at the time surface tile construction is requested.
