Will it count as a sin if I am summoned via white soap stone to fight other in my covenant

Important note that isn't mentioned in ANY of the Wikis. When you join the Forest Hunter covenant, regardless of how you do it (abandoning other covenant or not being in any covenant), will make you sin. I couldn't find any apparent harm, as in, anyone acting hostile towards you or denying any services, but it is apparent and you can test it: 1. Start at Oswald, making sure 'You have not sinned'2. Run to Alvina without killing any of NPCs3. Answer her questions correctly and join the covenant4. Make sure nothing's bugged, no NPCs died and you aren't attacked by NPCs5. Run straight back to Oswald6. Use the 'absolve sin' option and see that you, in fact, have sin now, simply by joining Forest HuntersSeriously. Not a single wiki lists this and it's quite major, in my opinion. I wanted to do a 'no-sin' walkthrough and was quite perplexed to see it's impossible to do if I also want to join this covenant at any point of the game...

Is it possible to still invade others players this many years after the games release? So far I haven't found anyone and was hoping to get the ring of fog

Clarification Needed - Wiki States: This is the one and only covenant that has no betrayal penalties and also has the helpful effect of deflecting other betrayal penalties. If you join this covanent (after abandoning another without Oswald's help) you will not receive the penalties of leaving that previous covenant.

Example: I'm level 2 in Chaos Servants and have not yet unlocked the shortcut door to Lost Izalith. If I join Forest Hunter covenant and abandon my current covenant will I retain my level 2 rank? Or will I get normal betrayal penalties and get ranked down to level 1?

I would love an answer. If it's wrong then it's pretty harmful misinformation.

There's, I think, a really rare bug that is not related here. You can be summoned as covenant invader in the Darkroot Garden in a world where the gate is not opened. Of coursly there's nobody to kill and you have to wait the host die by himself or you to go back to your world.

Decided to do some PvP with this covenant in NG+, 5 hosts were killed (I know they were hosts since I received a pendant, two chunks and two large shards after all of that). I talk to Alvina after 4 kills and she does not give either reward, no divine blessing or fog ring. After the fifth kill she talks about how suspicious Shiva is, then resumes the same "how ya doin' out thar?" dialogue. What's going on here? Is the covenant bugged? Did I not follow some esoteric procedure that prevents me from obtaining the rewards for good? Not that it's THAT big a deal, I already have a fog ring from a Snuggly trade (can that cause issues?) and divine blessings aren't that terribly hard to come by (I have eight of them) but it's the principle of the matter more than anything.

Trophy still not unlocking. Have the official guide and followed each step. Ridiculous.

Question is okay to leave the covenant kill the npcs in the forest then rejoin or do I have to request my sin to be removed before they calm down
