--- Comment #16 from Anastasius Focht focht@gmx.net 2013-12-05 02:16:50 CST --- Hello GyB,
that looks like a small script/text file. I checked the log and the size is always reported with 716 bytes.
Looking for reasons for this kind of error message I found this:
https://github.com/Facepunch/garrysmod-issues/issues/84
--- quote --- Noticed steam is retrieving a particular file on each cache verification. ... [2013-06-09 22:34:29] Validating files (active,full) ... [2013-06-09 22:36:14] Validation: size mismatch ... ... Possibly validating against the wrong code branch? Also, character case mismatch on the path again. --- quote ---
Maybe the server (database) metadata (length, SHA1) is somehow wrong/inconsistent, pointing to a different version of the actual content.
Do you have a Windows machine by chance (VM?) to check the file size and content of "installscript.vdf" against the file in Steam WINEPREFIX (just download, install, re-validate content)?
