Russian Language Version translated by kokokobana aka cat-boy
REQUIREMENTS:
+ Automatron DLC
+ Far Harbor DLC
FEATURES:
+ Various new locations to explore.
+ Roughly 20 quests. Several with multiple solutions for completion, and some with unique rewards.
+ Three voiced companions with full affinity, including romance options, perks, companions quests and reactive dialogue.
+ Over three thousand unique lines spread out across nearly 50 NPCs.
COMPATIBILITY:
+ Any mod that alters the Commonwealth world space cell BackBayFence01 or uses radio frequencies 106. 55, 107. 64 or 107. 65 may present compatibility issues. It's possible conflicts might arise in other ways but these are the most likely.
+ The Player is mute in all mod-related dialogues. To avoid the awkward long pause, we have placed detailed dialogue in the conversational prompts. We suspect mods that circumvent the dialogue choice prompts may lead to the player having blank dialogue choices.
+Using Renner Destructible Lights Mod is known to cause CTD at The Temple of Transmission and possibly Plum Grove. Credit to koalayung for discovering the conflict.
KNOWN ISSUES:
Any substantial bugs or issues we encounter will be listed. Please report any game-breaking bugs you encounter to this mod's discussion forum. Additionally, please be thorough in helping us to understand what went wrong. Any information that could lead to us recreating the problem is very much appreciated when making your post!
+ Some people have mentioned that the 'Odd Broadcast' is silent for them, and due to this do not know where to start. You CAN start without the broadcast. Search the vicinity of Trinity Tower and Layton Tower for a location called Plum Grove. You're good to go once inside.
+ There have been some reports of NPCs locking up during their dialogue. We're not sure what could be the cause of this, as it seems to crop up randomly. Possible remedies for this are turning away from the NPC to exit dialogue, punching them, or lastly reloading from the game's main menu.
+We have had some reports of the mod installing incorrectly when using NMM. If you are running into irregularities, such as missing audio for lines or invisible armor, then check Fallout 4's Data folder. If you do not see The Code - Main. BA2 and The Code - Textures. B
