Single backslash rstripped in input

[YumYummity]

Describe the bug
A single backslash can be placed at the end of an integer.
EG. -slots 200000\ results in the same thing as -slots 200000

To Reproduce

# using guilded.ext.commands.Bot
@bot.command(name='slots')
async def testcode(ctx, amount:int):
    await ctx.reply(str(amount), private=ctx.message.private)

Afterwards, just run -slots 200000\

Expected behavior
Raise an error: Converting to "int" failed for parameter "amount".

Actual behavior
Command runs as if the backslash isn't there.

Not sure what's causing this, it's stripped from string arguments too. Seems fairly inconsequential but I'll keep it open as a reminder to look into it.

This only happens for a single backslash, and it gives the correct input if you have 2 or more backslashes.
