    - Added force to chunk checks so other forces entities will not be considered when a ghost is placed from another force.
    - Expanded minimum chunk check range so item-request-proxies / missing modules would be found in single entity construction if they got missed somehow.
  Bugfixes:
    - Various crashes due to lack of entity validation.
  Info:
    - Landfill can be enabled or disabled through the mod settings menu.
    - Landfill functionality is highly experimental and does not represent the finished product.
    - Landfill is best constructed in small jobs close to the shore. It is highly recommended to have atleast a few Constructrons placed.

    - Constructing landfill will likely cause inefficient behaviour of Constructrons until the job is complete.
  Known issues:
    - After job time out, Constructrons will attempt to finish the build or deconstruction queue even if the inventory is full.
    - If something happens to the Constructron during an active job it continues as if nothing is wrong. There are checks in place to queue another job however.

    - Constructrons that are already on the way to repair an entity that gets repaired by a local robot will still proceed as the job is already in progress.
    - If you find there are too many repair jobs that are fulfilled by robots the advice is to lower the repair % or toggle the repair jobs to OFF.

    - After job time out, Constructrons will attempt to finish the build or deconstruction queue even if the inventory is full.
    - If something happens to the Constructron during an active job it continues as if nothing is wrong. There are checks in place to queue another job however.
