Thanks, problem solved, deleting temporary files worked for me (Locus Pro 3.1.3). One small drawback is that this operation clears data for all maps so all maps are reinitialized after restart. This is time consuming but yes - it was exceptional situation so its OK.
Note:
The corrupted and new TAR files in atlas had the same length and create date so the Locus probably didn't detect file rewrite.
But what is surprising is that Locus generated tiles interleaving after whole atlas (folder in /map/ with TAR files) was deleted and uploaded (with correct TAR file). Of course I started Locus between deleting and uploading to release atlas from _store_map_files.lb in Locus/cache/map/init but I didn't check it. Now I am not able to recreate this behaviour.
