DLC Incompatible [NOT A BUG]

[Ole'Trkr]

Steam user....I'm running 1.27.1.21s version. Downloaded the DLC Heavy Cargo Pack and this is the message I get when starting game.

INCOMPATIBLE DLC - Part of the currently installed downloadable content is not compatible with the current version of the game and will be disabled. Please verify integrity of the Steam game cache. The following content is incompatible: DLC - Heavy Cargo.

Any suggestions on what to do ? Thanks.

I verified integrity of game files in Steam, didn't help.

As people here saying in other topics, current game version is 1.27.2.1.
According to SteamDB the temporary_1_27 branch was not updated, so if you use this branch just switch to the public one (opt out of betas) in Steam game options.
