Q: Placing the little orange square at the end of the Exercise environment from Legrand Book Orange template I wrote the notes of one of my courses using the very nice Legrand book template, but I have a little problem with those little orange squares at the end of the exercises. When I write \begin{exercise} .. \end{exercise}, the little square at the end of the box is sometimes badly placed.
Precisely, if the exercise ends with a formula like \[ ... \] or a list \begin{itemize} ... \end{itemize} then that little square goes to the next line. That, in a few cases, means that it goes on the next page, making the exercise box split into two pages, with just that little orange square on the second page, very bad. 
I fixed a similar issue with the bigger black box of the 
\begin{proof} .. \end{proof} environment by placing a \qedhere inside the  \[ ... \], but the same command does not have any effect inside a \begin{exercise} .. \end{exercise} environment.
I have the same problem with the \begin{example} .. \end{example} environment. Is there any command like  \qedhere  working there?
Edit: reading an answer to a different question here I tried to put \vspace{-\baselineskip} before the \end{exercise}. The result was unexpected: the orange box reduced exactly of the expected amount but the square remains were it is, so it is now out of the box!
Edit 2: The  screenshot 

is my try to produce a minimal but complete example as requested by @@CarLaTeX in the comments. I produced it by using the online Legrand Orange Book Template here:

A: Wow, this is really worst template I have ever seen. Don't use it unless it is the only chance to safe your life. If someone is forcing you at gun point to use this template, then you could workaround the problem shown in the question by enlarging the page in question by one line. In all other situations, the problem is best solved by deleting all files are associated with this template.
(placing a square at the end of an exercise is also very strange, it should only be placed at the end of proofs...)
