Having trouble to solve same problem twice or more

[AndradeTiago]

Hello,

I'm having some trouble solve the same problem twice without rewriting the entire model

Here an example:

---

using Complementarity using JuMP

m = MCPModel()

@variable(m, x>=0) @mapping(m, F1, 2-x) @complementarity(m, F1, x)

solveLCP(m) solveLCP(m)

---

In the second solve attempt, it returns the following error message. It happens independently if I'm trying to solve each attempt with path or nlsolve.

Thanks. I need to look into this issue. Will need some time though.

Model reuse should now work in the master branch. However, it is still experimental. If you find any error or issue, please let me know.
