I have found out the cwr3_rhs_to_cwr3_compat_vehicles mod is mentioned in the mission.sqm. I will have to publish a hotfix for this mission. Please standby.
You can also enable this mod, finish the mission and then remove the mod. The next mission will have to be reverted.
The mod can be subscribed at https://steamcommunity.com/sharedfiles/filedetails/?id=2949105329.
THe mission is "Hostages", it comes after the mission where you defend the town from tanks with thanks. I seems that no way I can revert or resume the mission, I just can't access it and my PC hangs. I did play it before, but I didn't pass it. So it worked before but not anymore.
I learned to track down, when what has updated, and it was only this Resistance which was updated 19.3.2023. Revering or resuming will crash entire Arma3 right now. I did delete and unscriibed from Resistance compaing, and then re-downloaded it. I then created new MOD list (I have 11 mods, 9 required + additional mission packs). I then reset the compaing and started from beginning, using the SKIP code/cheat. I managed to skip several missions (I played before last week already), but this mission I am stuck to, again failed Arma. The mission is when you free hostages and then go up to the hills to attack the base. I can provide better details later. I now try to reboot again and revert the mission again.
