UNICODE_FSS has three-byte characters. A varchar(200) will have a length
of 600 bytes. A varchar(255) will have a length of 765 bytes. Are you
sure your tools are not showing you the byte length, rather than the number
of characters?

Exactly what change did you do to the parameter that is being reported with
a length of 3000?

If you have an index on a unicode column, both 200 and 255 would be well in
excess of the implementation limit (which will be about 65 characters,
perhaps less, if you have a collation order defined). Did you change the
column sizes of any indexed columns in the same script?
