Hey there, the plugin is broken as of todays update. :-)

It generally helps to include the error so the dev knows where to look in the code

Failed to compile: SamSiteMap.cs(151,54): error CS1061: Type `SamSite' does not contain a definition for `scanRadius' and no extension method `scanRadius' of type `SamSite' could be found. Are you missing an assembly reference?

Last Update Rust!

SamSiteMap - Failed to compile: SamSiteMap.cs(136,54): error CS1061: Type `SamSite' does not contain a definition for `scanRadius' and no extension method `scanRadius' of type `SamSite' could be found. Are you missing an assembly reference?

Well I'm sorry, I'd have assumed that they would be able to investigate it anyway as they have done in the past..

Plugins often receive false reports of issues due to user error or unrelated issues, so devs will often not investigate without sufficient information or proof of issue.

I phrased that a bit poorly. It was intended as helpful information next time you have a plugin issue, not an accusation.
What I meant was similar to what WhiteThunder said:   Just saying "it doesn't work" isn't enough for the dev to figure out.  It could be something wrong at your end, a conflict with another plugin, complete user error, or (in this case), changes in the mod framework.  Providing as much information as possible (error message at a minimum) helps the dev focus on the issue, and gets it fixed faster.  

Merged post

update:  based on the fix for RaidableBases (which had the same error), the solution is as follows:
edit line 149 and replace "samSite.scanRadius" with "samSite.missileScanRadius"

I submitted a patch using vehicleScanRadius (150m) instead since missileScanRadius (225m) is for MLRS rockets. The plugin maintainer (or Wulf) will merge it.
