We don't have an active user base large enough to support a 100 seat chamber. If this is a simulation of a Western democracy then parliament must be made smaller. I cannot think of one Western legislature that allows absentee proxy voting; all have complicated "pairing" arrangements for missing MP's, but I don't see that working here, hence the need for new rules before a new election is called.
Proxy Voting
According to Robert’s Rules of Order, 1896, parliamentary procedure is based on the consideration of the rights: of the majority, of the minority (especially a large minority greater than one-third), of individual members, of absentee members, of all of these groups taken together.
It is unknown to a strictly deliberative assembly, and is in conflict with the idea of the equality of members, which is a fundamental principle of deliberative assemblies. There can be but little use for debate where one member has more votes than another, possibly more than all the others combined.
ps. The reason there are so many edits in my last post is that I added this after you had posted and took it away to post here.
