Failed to load class files of expansion

[masterhacka]

Placeholder API is dropping sometimes the following issue on startup an no of the extensions are going to work. What can I do?

I am getting the exact same error, however, it only happens half the time I boot up my server and for some reason it only affects this other server host I am moving to, but not the other one I have been using this expansion on for months.

After a ton of testing I have confirmed a couple of things. For one, this bug appears only on startup and if you reload the plugin even after it stops working due to this error it will reload perfectly fine. I have also confirmed that it is not a problem with any custom javascript files as even without them and with the expansion booted up for the first time it can still do this. Now I have no idea why this only happens about half the time when booting up, it points to it being a compatibility error with some other plugin or something like that, but then again, why isn't it happening on my main server and only on this other server when they are on basically the same backup? I don't know, but I have ran out of clues and ideas.
