 If lastile buffer is larger then tilesize then lastile simply stops
lastile64.exe -i in.laz -tile_size 50 -buffer 250 
 gives
ERROR: buffer 250 is larger than tile_size 50

Would it be possible to make it a WARNING instead of simply stopping the script and allow the process to continue?

It plays a big role when the point density is large and you want to classify large warehouse buildings.

If the point density is so high, then you almost certainly don't want
the extra overhead of having to process every single point 121 times!

I strongly suggest you instead look at downsampling the point cloud to a
density which is better suited to the size of the features you are
trying to extract.

For my orienteering maps I also find industrial buildings in some areas,
but I will much rather accept that they initially can end up in 2 or
more tiles.

Anyway, the idea behind buffered tile-based processing is to allow every
tile to be handled in isolation, on arbitrary many processing cores.
