Trees Of Stages

Dear devs,

I recently requested that the Trees Of Stages mod be added to aternos and it was quickly added. I put the mod in my mods folder and added it to my mods list on the server. However, now every time I try to join my server, minecraft gives me a pop-up notification at the top-right corner of my screen telling me that 'Trees Of Stages has caused a problem' (or something along those lines). Then, underneeth that pop-up, a few more notifications show up all saying that 'and unknown problem has occurred (or something similar), shortly before crashing. Both the mod in my mod folder and the one the server uses are the same versions. What is causing the problems and why is my game crashing?

Kind regards,
Hesse

Here are the screenshots

I don't get redirected. If i wait on the 'logging in' screen for too long, the game just crashes and stops working. When I click on 'cancel' on time, the notifications stay on the screen, even when I go to the main screen. These are the only messages I get.

Client log: https://mclo.gs/2avqM8F
Server log: https://mclo.gs/SbcaGJy

I'm not entirely sure if these are the right logs. Not much of a tech guy. These are the ones when I googled 'aternos client log' and 'aternos server log' and followed the link on the top page.

whats the difference between the two and where can I find the client/server log?

Server log: https://mclo.gs/L51pjra

Client log: which one do you need? I added a screenshot of all the latest logs

I'm assuming that's just the latest 2020-05-09 file right? Or do you need the debug file? When I try attaching the file it says "the file extension is invalid"

(I'm sorry this is taking a little long due to my incompetence when it comes to files etc)

I put the latest regular log into a .zip file, which allows me to share it

If those mods are the problem, then I'd rather just leave out Trees of Stages. Is there no way to have all of them together on a server? I have no problem combining them on a regular world. Isn't it weird that Trees Of Stages doesn't work?

But there's no way to fix it without removing any mods? Perhaps something went wrong with adding the mod to aternos? I haven't experienced the issue with any other mods

Alright, I guess it's just bad luck then. Thanks for the help! Have a good day!
