Welcome to our Forum, Jurk0wski.
I read through your list of questions and was prepared to give answers, but it looks like others beat me to it. Did you get everything you needed answered satisfactorily?
Also, you used some abbreviations in your posts, such as SSs and TLDR. We ask that members not use abbreviations because not everyone on the forum will know what they mean. I, personally, don't know the meaning of either of the two I just mentioned.
Lastly, you missed some capitalization in your posts and I'm going to edit them to make corrections. I hope you don't mind. And if you would watch those in future posts, I'd really appreciate it.
Edit: Thank you for editing out the name of the mod. It's correct that we don't allow discussions of specific mods or links to them.
This I need to ask. I DESPISE traveling. I hate it with a passion due to all the bugs it causes. so, my question is simply this: can I use buydebug solely to buy nectar machines? I don't need them, but they're nice to have, and I'd really rather not risk traveling to get them. (I can get the books and such from the consignment store if I look enough, not sure about the machines). If I cannot, I revert to my previous question about saves. Can I backup my town before traveling, travel, buy what I need, leave, and check to see if it's corrupted, and if it is, revert?
I didn't see this question addressed. No, you may not use Buydebug for nectar machines. You'll have to travel to get them or do without. It's always a good idea to save your game before traveling. If you travel and get a game-breaking bug, yes, you can revert to a previous save. If it's a genuine technical breakdown, it's fine to revert. You may want to leave a note here for Metro just to let him know what you did.
