Help/Support "found ambious match" using .net reflector, reflexil add-in

[0utlaw_ 0 Galaxy S6 Edge Nougat]

Hello. As the title says, i am hacking an "Assembly-CSharp.dll" file with .NET Reflector. There are multiple functions with the same name (overloaded). Only a single function, or in some cases, no functions with the same name can be opened, throwing that error. For example keywords:

"openchest". It has OpenChest() function, some <OpenChest> list thingy and another OpenChest(a couple of parameters here). None of them work.

"upgradecar". It has a single function UpgradeCar(a couple of parameters here) although i can't open it.

"getpirce". It has GetPrice(a couple of parameters here) which i can't open, and a GetPrice() which i am able to open.

Until now i figured only those 3 cases. Does anyone know the solution so i can open multiple functions with the same name? Thank you.
